Question

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

Evaluate

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

Solution Steps

Multiply $-1$ and $2$ to get $-2$.

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

Use the distributive property to multiply $-2$ by $a+1$.

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

Use the distributive property to multiply $-2a-2$ by $x$.

$$x^{2}-2ax-2x-2a+1$$

Expand

$x^{2}-2ax-2x-2a+1$

Solution Steps
