5x2 + x + 7 cannot be simplified.
35 + 40x + 5x2 = 5(7 + 8x + x2) = 5(7 + x)(1 + x)
3x
Divide all terms by 5 and so x^2+6x-55 = (x+11)(x-5) when factored
X= -2
x + 5 + 4 = x + 9
You can expand the first expression in parentheses, then add or subtract like terms.
x(x + 2)
15
The answer is 5x+3y. (5 xs and 3 ys)
- - x + 3 = x + 3
-9
13x+27=3x+32 Reorder 13x-3x=32-27 Simplify 10x=5 Simplify x=5/10 Simplify x=1/2 Answer
