Answer:
15r² - 14x - 8
Step-by-step explanation:
- 5x * 3x = 15x²
- 5x * -4 = -20x
- 2 * 3x = 6x
- 2 * -4 = -8
Now add your products,
15x² + -20x + 6x + -8 = 15x² - 14x - 8
It would be 25.6 with a dash on top of the number 6
Plug in 2 for x, and -4 for y
2(2)² + 3(2)(-4) - (-4)²
2² = 4(2) = 8
3(2) = 6(-4) = -24
-4² = 16
8 - 24 - 16 = answer
Simplify.
answer = 8 - 40
answer = -32
-32 is your answer
hope this helps
