Solve the equation. x2 + 10x + 24 = 0 a) -12 and 2 b) 12 and -2 c) -4 and -6 d) 4 and 6

Option C

Step-by-step explanation:

Given a quadratic equation

x^2+10x+24 =0

We can use either formula or factorization method to solve this equation.

The last term is 24, it is a product of 6 and 4. Sum =6+4 =10

Hence factoring can be done easier

Split the middle term as 6x +4x

x^2+6x+4x+24 =0

x(x+6)+4(x+6)=0

(x+4)(x+6)=0

Either x+4 =0 or x+6 =0

x=-6 or x =-4

Thus solution for this equation is option C

i think that you should ask google for the answer to that problem because if we don't know it google does

9 x 8 divided by (5-3)=36
