Question

can someone please explain to me how to solve this problem? 5(7-x) + 6x(3x+4)

Answer 1

I meant how to simplify it:)

Answer 2

yea you want to distribute the outside numbers so 5(7-x) = 35 - 5x
the 6x(3x+4) = 18x^2 +24x
so combine that and you get:
18x^2+ 19x + 35

Answer 3

can you simplify any more than that?

Answer 4

that's fully simplified

Answer 5

ok thanx I just thought that the 18x^2 and the 19x could be combined but I'm probably just remembering it wrong:)

Answer 6

solve it using long division method..
