All zeros of the polynomial function 3x^3 + 2x^2

Softa [21]

Answer:

$x = 0, -2/3$

Step-by-step explanation:

Step 1: Factor out an x^2

$3x^3+2x^2$

$x^2(3x + 2)$

Step 2: Find the zeros

$\sqrt{x^2 } = \sqrt{0}$

$x = 0$ → Double Root

$3x + 2 - 2 = 0 - 2$

$\frac{3x}{3} = \frac{-2}{3}$

$x = -2/3$ → Single Root

Answer: $x = 0, -2/3$

Part A. Solve -np - 80 < 60 for 'n'. Show your work.

skelet666 [1.2K]

Part A:
- np -80 <60
Adding 80 both sides
- np < 140
Dividing by -p both sides
n > -140/p
Part B:
2a - 5d =30
5d = 2a-30
d= (2a-30)/5
