What two steps are necessary to put this equation into standard form?

x^2-3x+27=8x-3

a. add 3 to both sides and subtract 8x from both sides.
b. add 3 to both sides and add 8x from both sides
c. the equation is already in standard form
d. subtract 3 to both sides and subtract 8x from both sides

hello from mrbilldoesmath!

answer:

25x^2 + 90x + 84

discussion:

mn(x) = m(n(x)) = m( 5x + 9) =

(5x + 9)^2 + 3 =>

25x^2 + 90x + 9^2 + 3 =

25x^2 + 90x + 84                 (as 9^2 = 9*9 = 81)

which is the second choice
