The first one has to be solved with the quadratic formula, I know how to solve it with other methods but when I use quadratic, I keep getting wrong answers..... The second one has to be solved with completing the square method.. 7 Likes 1 Share |

(1) x²+2x-8=0 x²+4x-2x-8=0 x(x+4)-2(x+4)=0 (x-2)(x+4)=0 x=2 or x=-4 {x} = {2,-4}.... (2) x²-3x-18=0 x²+3x-6x-18=0 x(x+3)-6(x+3)=0 (x+3)(x-6)=0 x= -3 or x=6 { x } = {-3,6 } 425 Likes 39 Shares |

Chimaobi302:I know how to solve them like this, you solved them by factoring right? I said the first one should be solved with Quadratic formula a.k.a, Almighty formula .... While the second should be solved with Completing the square method ....Thanks though.... Anytime I use those two methods to solve the questions respectively, I always end up with the wrong answer. I just want someone to solyit using those methods so that I can study their solutions and figure out what I'm doing wrong. 25 Likes 3 Shares |

AI got your number done. x = (-b ± √(b²-4ac)) / 2a Where a = 1, b = 2, and c = -8. so x = (-2 ± √(2²-41(- ![]() so x = (-2 + 6) / 2 = 4/2 = 2 or x = (-2 - 6) / 2 = -8/2 = -4 So the solutions are x = 2 and x = -4 18 Likes 1 Share |

NDSMELODY:This is Difference of two squares a²-b² = (a + b) (a - b) What you did on the left hand side was you factored the perfect square. You rewrote the trinomial on the LHS in the perfect square format. That's different from Difference of two squares 10 Likes |

I want to implore Nigerians not to follow aba made fake product but the original tested n trusted man Imagine a man that made doctors go on strike for 13 months telling u he will do well in health sector? Isn’t it laughable Imagine a man who refuse to pay lecturers for good 6 months telling u he values education n to add insult on injury he increased ANSU tuition fee by 200% Isn’t it laughable? Imagine a man who fails to conduct local government election for good 7 years telling u he will deliver dividends of democracy to u, y didn’t he to that when he was governor? Imagine a man who can’t manage a majority Christian state n even had to start divide n rule between catholic n others Christian’s telling u he will unite u No b craze b dat? The same man who killed youths extrajudicially n dumped their bodies inside awkuzu river telling u he will protect the youth, Nigerians ronu He’s telling u he will move us from consumption to production but he’s the greatest importer of what his brothers are manufacturing locally Same man that claim he needs to b stingy by denying people dividends of democracy is stashing money into teenage daughter n even have numerous offshore s The same man who said he wants to change d old order still romancing obj, ibb, enenche of endsars n the latest the billionaire grass cutter In Sowore voice…. A thief can’t fix your window This is what Owobokiri has to say about him then, ask him what has changed today? 5 Likes 2 Shares |
