Step-by-step explanation:
<u>Step 1: Define</u>
f(x) = 8x² + 5x - 2
x = -2
<u>Step 2: Evaluate</u>
- Substitute in <em>x</em>: f(-2) = 8(-2)² + 5(-2) - 2
- Exponents: f(-2) = 8(4) + 5(-2) - 2
- Multiply: f(-2) = 32 - 10 - 2
- Subtract: f(-2) = 22 - 2
- Subtract: f(-2) = 20
Answer:
16
Step-by-step explanation:
24 minus 8.
The reason I subtract 8 from 24 is because the eight is a <u><em>negative</em></u>. Also, you can do it the opposite way like -8 ADD 24 on so you'll end up with 16 but it's a longer process.
(X+3)(x-4)(2-+3) i believe is the answer and I’m so sorry if it’s wrong
