Answer:
1) (3c + 1 )(3c + 2)
2) 8x^2 + 26x - 7
3) 6
4) 16x^2 - 48xy^3 + 36y^6
5) (5x - 2y)(2x - 5y)
Step-by-step explanation:
1) 9c^2 + 9c + 2 = (3c + 1 )(3c + 2)
2) (4x - 1)(2x + 7)
= 8x^2 + 28x - 2x - 7
= 8x^2 + 26x - 7
3) 7m^6n^5
Highest degree is 6 (m^6)
answer: 6
4)
(4x - 6y^3)^2
= (4x)^2 - 2(4x)(6y^3) + (6y^3)^2
= 16x^2 - 48xy^3 + 36y^6
5)
10x^2 - 29xy + 10y^2
= (5x - 2y)(2x - 5y)
because if if distribute (5x - 2y)(2x - 5y)
= 10x^2 - 25xy - 4xy + 10y^2
= 10x^2 - 29xy + 10y^2
