Math Problem Statement

The polynomial 8x2 – 8x + 2 – 5 + x is simplified to 8x2 – gx – h. What are the value of g and h?

g = –9 and h = 7

g = 9 and h = –3

g = –7 and h = 7

g = 7 and h = 3

Solution

To solve for the values of gg and hh, let's simplify the given polynomial step by step.

The given polynomial is: 8x28x+25+x8x^2 - 8x + 2 - 5 + x

First, let's combine like terms:

  1. The x2x^2 term: 8x28x^2 (no other x2x^2 terms to combine).
  2. The xx terms: 8x+x=7x-8x + x = -7x.
  3. The constant terms: 25=32 - 5 = -3.

So, the simplified polynomial is: 8x27x38x^2 - 7x - 3

We are told that the simplified form is 8x2gxh8x^2 - gx - h.

By comparing the coefficients, we can see that:

  • g=7g = 7
  • h=3h = 3

Therefore, the correct values are: g=7andh=3g = 7 \quad \text{and} \quad h = 3

The correct answer is:

  • g=7g = 7 and h=3h = 3
