Question

Evaluate the following expression for x = -8 and express in simplest form:
x²-3x+7

Answer 1

To evaluate the expression x²-3x+7 for x=-8, you substitute -8 into the equation resulting in 64+24+7, which simplifies to 95.

Step-by-step explanation:

To evaluate the expression x²-3x+7 for x = -8 and express it in simplest form, we need to substitute -8 for x and simplify the result:

1. x² becomes (-8)², which is 64.
2. -3x becomes -3(-8), which is 24.
3. Now, combine these values with +7: 64 + 24 + 7.
4. The simplified result is 95.

The expression evaluated at x = -8 gives us 95 as the simplest form.
