Solve the expression... 9x(4x + 7)
First: eliminate the parenthesis > use the Distribution Property in which, you multiply the outer term with the terms in parenthesis.
9x(4x) + 9x(7)
36x^2 + 63x

multiply 9x by both terms in the parenthesis.
9x X 4x = 36x^2 ("^2" is to the 2nd power or squared.)
9x X 7 = 63x
and since its 4x PLUS 7. you put an addition sign in between those two "new terms," getting:
36x^2 + 63x
you can arrange the terms vice versa. but its easier just do order from left to right.

take 9x and multiply by each term in the quanlity
9x*4x + 9x*7
= 36x^2 + 63x

all you have to do is take 9x and multiply it to each term.
9x(4x+7)
36x^2+ 63x

9x X 4x = 36x
9x + 7 = 63x
so 36x + 63x = 99x

DISTRIBUTIVE property
a( b + c ) =ab + ac
9x ( 4x + 7 ) = 9x* 4x + 9x * 7
= 36x^2 + 63x
Hope this will help you ..:)

9x(4x+7)=
9x*4x=36x^2
9x*7=63x
36x^2+63x

9x times 4x equals 36xsquared + 9x times 7 = 63 x
so 36xsquared +63x
But
