Answer 2

factor

Answer 3

after i come up with two numbes that add up to middle term im lost

Answer 4

a^2(35a^2+9a-2)=a^2(7x-1)(5x+2)

Answer 5

its suppose to be a^2(5a+2)(7a-1)

Answer 6

35a^4+9a^3-2a^2 = ( 7a^2 -a ) ( 5a^2 +2a ) = a(7a-1) a(5a+2)=a^2(7a-1) a(5a+2)

Answer 7

opps ur right

Answer 8
