Solve 4*x^2-x-(a+1)(a+2)

$$4 \cdot x ^ { 2 } - x - ( a + 1 ) ( a + 2 )$$

Evaluate

$$-\left(a+1\right)\left(a+2\right)+4x^{2}-x$$

Solution Steps

Use the distributive property to multiply a+1 by a+2 and combine like terms.

$$4x^{2}-x-\left(a^{2}+3a+2\right)$$

To find the opposite of a^{2}+3a+2, find the opposite of each term.

$$4x^{2}-x-a^{2}-3a-2$$

Expand

$$4x^{2}-x-a^{2}-3a-2$$

Solution Steps

Use the distributive property to multiply a+1 by a+2 and combine like terms.

$$4x^{2}-x-\left(a^{2}+3a+2\right)$$

To find the opposite of a^{2}+3a+2, find the opposite of each term.

$$4x^{2}-x-a^{2}-3a-2$$
