X 3 plus x-142 plus x is an equation equal to x3+2x-142.
x2 + 4x + 3 =(x + 3) (x + 1)
7x + 3 t +jjakw
x^3 + ax + 3a + 3x^2 = (x^3 + 3x^2) + (ax + 3a) = x^2(x + 3) + a(x + 3) = (x + 3)(x^2 + a)
The answer is 5x+3y. (5 xs and 3 ys)
It is 123.99
When x = 3, 3 plus x = 6.
X2+3x+x+3=x(x+1)+3(x+1)=(x+3)(x+1)
x = 0
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
Yes. According to the commutative property of addition: x + 3 = 3 + x
x+3-x= x-x+3 = 3
(x + 3)(x + 3)
