Simplify (x^2+x-12)+(x^2-8x+16)

$(x^{2} + x - 12) + (x^{2} - 8 x + 16)$

Step 1

Remove parentheses.

$x^{2} + x - 12 + x^{2} - 8 x + 16$

Step 2

Add $x^{2}$ and $x^{2}$ .

$2 x^{2} + x - 12 - 8 x + 16$

Step 3

Subtract $8 x$ from $x$ .

$2 x^{2} - 7 x - 12 + 16$

Step 4

Add $- 12$ and $16$ .

$2 x^{2} - 7 x + 4$
