Answer: 8x³ + 12x² - 16x - 16
<u>Step-by-step explanation:</u>
(4x² - 2x - 4)(2x + 4)
= (2x + 4)(4x² - 2x - 4)
= 2x(4x² - 2x - 4) + 4(4x² - 2x - 4)
= 8x³ - 4x² - 8x + 16x² - 8x - 16
= 8x³ + (-4x² + 16x²) + (-8x - 8x) - 16
= 8x³ + 12x² - 16x - 16
1) -(5.8x14) = -406/5 = -81.2
2) (-1/3)(-1) = 1/3 = 0.3333333....
3) -2 + 1/4 / 1 + 1/2
-7/4 / 3/2
-1.75 / 1.5 = -7/6 = -1.166....7
What do you mean by “and”?????
Is it divided or add??
I’m only sure about the first one but tell me what and mean
Answer:
Step-by-step explanation:
(x-3)(x-3)(x²)(x+2)
(x²-6x+9)(x³+2x²)
x^5+2x^4-6x^4-12x^3+9x^3+18x^2
x^5 - 4x^4 - 3x^3 +18x^2
