Question

(12x ² - 6x + 7)-(--20x ² -7x + 18)=
With solutions pls​

Answer 1

Answer:

32x²-13x+25

Step-by-step explanation:

(12x ² - 6x + 7)-(-20x ² -7x + 18)

= 12x² +20x²-6x-7x+18+7

= 32x²-13x+25

Answer 2

Given,

$(12x^{2}-6x+7)-(-20x^{2}-7x+18)$

We have simplify this given solution,

First we will apply the minus to $(-20x^{2} -7x+18)$

$=(12x^{2} -6x+7)+20x^{2} +7x-18$

$=12x^{2} -6x+7+20x^{2} +7x-18$

$=32x^{2} +x-11$

Therefore, the answer is $32x^{2} +x-11$.
