Question

x^2-5x-24=0   quadratic equation...explain while solving? step by step?

anonymous · Answer

factorizing: x^2-5x-24 = (x-8)(x+3) = 0
so x=8 and x=-3 are the roots

anonymous · Answer

how?how do you get x-8 and x+3?explain?

anonymous · Answer

factorizing..... if you multiplie the right side you get the same what's on the left. If you notice: (x-a)(x-b) = x2 -bx -ax +ab = x2 - (a+b)x +ab. So the sum with oposite sign is the x coeficient and the free term is the product. So just check posible factors of 24...

i know GT,but simply giving the answer doesn't always suffice..

anonymous · Answer

Then, you are supposed to ask what part of it you did not get. You never said anything.

anonymous · Answer

@GT is right. He gave you same explanation like i did....

anonymous · Answer

if you read the question,it says "explain while solving",not simply give the answer.
