Find the sum of -8x^2 -8x+10 and 5x+2

To find the sum of these two expressions, we must add them together.  This is modeled below:

-8x² - 8x + 10 + (5x + 2)

Because we are adding the expression in parentheses, there is no need to distribute the negative (only applies for subtraction) so the terms just keep their original signs and we can get rid of the parentheses.

-8x² - 8x + 10 + 5x + 2

Next, we must add together the terms that both have one variable x in them.  First, we can rearrange this expression so that these terms are next to one another.

-8x² - 8x + 5x + 10 + 2

Now, we simply add together the variable terms and the constant terms to simplify our expression.

-8x² - 3x + 12

Therefore, your answer is -8x² - 3x + 12.

Hope this helps!

(1,4) is on graph of f(x)

f(1) = 4

so 1/4 f(x)

1/4 f(1)

1/4. ×4

1

so point for function 1/4. f(x) is (1,1)

square root of 36/6 = 2.449489743

square root of 16/6 = 1.632993162

square root of 6 = 2.449489743

the answer is square root of 16/6 because the square root of 36/6 is the same answer as square root of 6 = 2.449489743
