what is a^2 + 10a+24

Answer:

Step-by-step explaintation

a2 + 10a = 24

10a + a2 = 24

10a + a2 = 24

Solving for variable 'a'.

Reorder the terms:

-24 + 10a + a2 = 24 + -24

Combine like terms: 24 + -24 = 0

-24 + 10a + a2 = 0

Factor a trinomial.

(-12 + -1a)(2 + -1a) = 0

Set the factor '(-12 + -1a)' equal to zero and attempt to solve:

Simplifying

-12 + -1a = 0

Solving

-12 + -1a = 0

Move all terms containing a to the left, all other terms to the right.

Add '12' to each side of the equation.

-12 + 12 + -1a = 0 + 12

Combine like terms: -12 + 12 = 0

0 + -1a = 0 + 12

-1a = 0 + 12

Combine like terms: 0 + 12 = 12

-1a = 12

Divide each side by '-1'.

a = -12

Simplifying

a = -12
