Sagot :

what formula is applied, I mean what method

Answer:

B

Step-by-step explanation:

We have the equation:

[tex]x^2+10x+24=0[/tex]

We can factor:

[tex](x+6)(x+4)=0[/tex]

By the Zero Product Property:

[tex]x+6=0\text{ or } x+4=0[/tex]

Solve:

[tex]x=-6\text{ or } x=-4[/tex]

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

Our answer is B.
