Question

Find the value of the greater root of x^2 + 10x + 24x = 0 a) -6 b) -4 c) 4 d) 6

Answer 1

what formula is applied, I mean what method

Answer 2

B

Explanation:

We have the equation:

`x^2+10x+24=0`

We can factor:

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

By the Zero Product Property:

`x+6=0\text{ or } x+4=0`

Solve:

`x=-6\text{ or } x=-4`

-4 is greater than -6, so -4 is the greater root.

Our answer is B.
