Answer:
Step-by-step explanation:
32²=(40-8)²
=40²-2(40)(8)+8²
=1600-640+64
=1664-640
=1024
also 32²=1024
Answer:
a) 
b) 
c) 
Step-by-step explanation:
<u>For the question a *</u> you need to find a polynomial of degree 3 with zeros in -3, 1 and 4.
This means that the polynomial P(x) must be zero when x = -3, x = 1 and x = 4.
Then write the polynomial in factored form.

Note that this polynomial has degree 3 and is zero at x = -3, x = 1 and x = 4.
<u>For question b, do the same procedure</u>.
Degree: 3
Zeros: -5/2, 4/5, 6.
The factors are

--------------------------------------

--------------------------------------

<u>Finally for the question c we have</u>
Degree: 5
Zeros: -3, 1, 4, -1
Multiplicity 2 in -1

Answer:
The answer is2nd point
Step-by-step explanation:

(x^4/3)×(x^2/3) = x^(4/3 + 2/3)
= x²

(x²)^1/3 = x^(2×1/3)
= x^2/3
Answer:
5
Step-by-step explanation:
9x+6y=-3
9x+6(-8)=-3
9x-48=-3
9x=45
x=5
