Question

In the factorization of 3x^2-20x-192=0, how can -20x be split into two terms?

Answer 1

Step-by-step explanation:

-20x should be split into 2 two terms in such a way that their product = -192×3x²= -576x² = -36x×16x

so, -36x+16x =20x

3x²-36x+16x-192=0

3x(x-12)+16(x-12)=0

(3x+16)(x-12)=0

3x+16=0, x-12=0

x=-16/3,12
