Solve 5a^2-4a+a^2-8a-a

$$5 a ^ { 2 } - 4 a + a ^ { 2 } - 8 a - a$$

Evaluate

$$a\left(6a-13\right)$$

Solution Steps

Combine 5a^{2} and a^{2} to get 6a^{2}.

$$6a^{2}-4a-8a-a$$

Combine -4a and -8a to get -12a.

$$6a^{2}-12a-a$$

Combine -12a and -a to get -13a.

$$6a^{2}-13a$$

Factor

$$a\left(6a-13\right)$$

Solution Steps

Factor out a.

$$a\left(6a-13\right)$$

Consider 5a-4+a-8-1. Multiply and combine like terms.

$$6a-13$$

Rewrite the complete factored expression.

$$a\left(6a-13\right)$$
