Answer:

Step-by-step explanation:
The zeros of the polynomial function are given us as -5,-1,2
If the zeros of a polynomial function are α,β,ω, the polynomial function can be obtained using the expression below:
f(x) = (x - α)(x - β)(x - ω)
where α = -5, β = -1, and ω = 2

<em>NB: To arrive at the answer, expand the brackets and after expansion, collect like terms to obtain the final answer</em>
Answer:
D. 2x^2 - 2x + 2
Step-by-step explanation:
(3x2 – 2x + 5) – (x2 + 3) add or subtract like terms
3x^2 - x^2 - 2x - 3 + 5 = 2x^2 - 2x + 2
Answer:
1.75 or 
Step-by-step explanation:
2.5 * 7/10 is just like 2.5 * 0.7
so 2.5 * 0.7 = 1.75
You could also convert 2.5 to fraction which is 25/10
so you would have
=
reduced would equal

For this case we have the following inequality:

Subtracting 4 from both sides of the inequality we have:

Dividing between 7 on both sides of the inequality we have:

Thus, the properties used were:
Subtraction property
