If
C=G - 3F
find the trinomial that represents C when F= 2x2 + 6x - 5 and G=3x2 + 4
C = G - 3F
when
F = 2x2+ 6x - 5
and G = 3x2 + 4
So we just have to substitute 2x2+ 6x - 5 in for F and 3x2 + 4 in for G
C = G - 3F
C = (3x2 + 4) - 3(2x2+ 6x - 5)
C = (3x2 + 4) - 3(2x2+ 6x - 5)
The next steps are to simplify expression.
First distribute the negative three to the terms in the parenthesees.
Second combine like terms.
