Question

What is the solution for x^2 + 4x = 96?

Answer 1

Are the solutions***

Answer 2

rewrite the equation as

\[x^2 + 4x - 96 = 0\]

the quadratic can be solved by factoring...

find the factors of -96 that add to 4

the larger factor is positive...

then its

(x + factor 1)(x + factor 2) = 0

hope it helps

Answer 3

The factors are 12 and 8?

Answer 4

Add to for though...

Answer 5

it***

Answer 6

nearly... so its 12 and -8

so you have

(x +12)(x -8) = 0

so if either binomial is zero, the equation is zero

so you need to solve for x, the following

x + 12 = 0

and

x - 8 = 0

and then you'll have your solutions.

Answer 7

-12 and 8?
