Math Help Factoring Polynomials

Question: Can someONE hELP ME ON A Couple of math questions.Factoring Polynomials?
Divide.
(3a^3 + 6a^2) divided by 3a
3a3 + 6a2 – 3a
3a3 + 6a2 + 3a
a2 + 2a
a2 + 6a2
5. Determine whether the polynomial is a perfect square and if it is, factor it.
n2 – 6n + 9
not a perfect square
is a perfect square: (n + 3)2
is a perfect square: (n – 3)2
is a perfect square: (n – 6)2
6. Determine whether the polynomial is a difference of squares and if it is, factor it.
y2 – 25
not a difference of squares
is a difference of squares: (y – 5)2
is a difference of squares: (y + 5)(y – 5)
is a difference of squares: (y + 5)2
thanks you guys
Answer: Divide.
(3a^3 + 6a^2) divided by 3a
= 3a³/3a + 6a²/3a
= a² + 2a
5. Determine whether the polynomial is a perfect square and if it is, factor it.
n² – 6n + 9
middle term = – 6n
= 2 ×√n³ × √9
= ± 2 × n × 3 = ± 6n
as middle term is – 6n it is a perfect square.
= (n – 3)²
6. Determine whether the polynomial is a difference of squares and if it is, factor it.
y² – 25
= (y)² – (5)²
= (y + 5)(y – 5)
is a difference of squares: (y + 5)(y – 5)

Polynomial Factorization Formulae
The following Polynomial Factorization formulae are useful when trying to factor any polynomials. In math, it is useful to know some important formulae to help you solve math problems. You should be familiar with the Polynomial Factorization formulae below. Although, when each Polynomial Factorization equation is common sense when you multiply them out, it is useful to be able to recognize the common standard Polynomial Factorization equations such as those below.
- (x + a)(x + b) = x 2 + (a + b)x + ab
- (ax + b)(cx + d) = acx 2 + (ad + bc)x + bd
- (a + b)(a + b)(a + b) = (a + b) 3 = a 3 + 3a 2 b + 3ab 2 + b 3
- (a – b)(a – b)(a – b) = (a – b) 3 = a 3 – 3a 2 b + 3ab 2 – b 3
- (a – b)(a 2 + ab + b 2) = a 3 - b 3
- (a + b)(a 2 – ab + b 2) = a 3 + b 3
- (a + b + c) 2 = a 2 + b 2 + c 2 + 2ab + 2ac + 2bc
- (a – b)(a 3 + a 2 b + ab 2 + b 3) = a 4 - b 4
- (a – b)(a 4 + a 3 b + a 2 b 2 + ab 3 + b 4) = a 5 - b 5
