- - x + 3 = x + 3
(x+3)(x+4) = x2+7x+12

3 + x - 5 = 03 + x = 5 x = 2
It is 123.99
250.00 x .03 = 7.50 + 250.00 = 257.50
When x = 3, 3 plus x = 6.
X2+3x+x+3=x(x+1)+3(x+1)=(x+3)(x+1)
x = 0
03 squared = 3 x 3 = 9

x + x + 1 + x + 2 + x + 3 = -144x + 6 = 144x = 8x = 2
x + 3 + 10 = x + 13
X 3 plus x-142 plus x is an equation equal to x3+2x-142.
x(x + 3) + 3(x + 3) = x2 + 3x + 3x + 9 = x2 + 6x + 9 = (x + 3)(x + 3) = (x + 3)2
