X= -2
x(x + 2)
Assuming simplify = factor...x3 - 3x + 2 = (x-1)(x2+x-2)
You can divide the integers in this case - 4 divided by 2 and 9 divided by 3. You would get 2 over x plus 3 over x. 4/2x + 9/3x = 2/x + 3/x = 5/x
3x^2 + x + 2x^2 = 5x^2 + x
11+(7-3)2=

Assuming simplify = factor...x3 - 3x + 2 = (x-1)(x2+x-2)
You can divide the integers in this case - 4 divided by 2 and 9 divided by 3. You would get 2 over x plus 3 over x. 4/2x + 9/3x = 2/x + 3/x = 5/x
3x^2 + x + 2x^2 = 5x^2 + x
x+6/2 = 9/5 Start x+3 = 9/5 Simplify 6/2 into 3 x + 3 = 1.8 Simplify 9/5 into 1.8 x = 1.2 Subtract 1.8 from 3 (or x = 6/5)
x - 2 over 2 - x = (x - 2)/(2 - x) = -(2 - x)/(2 - x) = -1.
Assume the expression is:4/(x + 2) + 6/(x + 5)Simplify this expression by combining the expressions altogether. Let's go step by step.Step 1: Determine the LCD of the expression.The LCD of the expression is (x + 2)(x + 5). Multiply the top and bottom of each fractional expression by whatever factor the denominator is missing!4/(x + 2) * (x + 5)/(x + 5) + 6/(x + 5) * (x + 2)/(x + 2)Step 2: Combine the expression and simplify.(4(x + 5) + 6(x + 2))/((x + 2)(x + 5))= (4x + 20 + 6x + 12)/((x + 2)(x + 5))= (10x + 32)/((x + 2)(x + 5))
-x - 2 + 15x = 14x - 2 = 2(7x - 1)
Factor it out: (x+2) squared
