Answer:
Option C
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
