Hello.

Parenthesis is going to be your best friend on this problem.

Let's write it out.

-10x² + 6x +5

- (-8x² +10x+5)

_________________ This becomes:

-10x² + 6x +5

+8x² - 10x - 5

________________ Now simplify. Parenthesis disappear because the negative/ subtraction sign has been distributed.

-2x² - 4x

Hope this helped.

mariarad [96]

(X)+(X+1)=24

"consecutive" means right after the other, so, if the first one is (X), the second integer <u>must be</u> (X+1). The answer 24 is given so you just have to solve the equation.

2X+1=24
2X=23
X=11.5
