Question

Solve 4x^2 = 12x + 40.

Answer 1

I solved it, and i'm not sure if it's right or not.. I got x = -2 and x = -5

Answer 2

x^2 - 3x - 10 = 0

=> (x-5)(x+2) = 0
=> x = 5 and x = -2

Answer 3

\[ 4x^{2} - 12x - 40 = 0 \]
\[x^{2} - 3x - 10 = 0 \]
Then Factor
\[(x-5)(x+2) = 0\]
So x = -2 and +5, you got it.
