2x8(x8) = (2)(x8)(x8) = 2(x8+8) = 2(x16) = 2x16
2x times 4x is 8x squared- then that times x is 8x to the power of three.Mathmatically represented as 8x^3
2x - (8 x 6) = 20 2x = 20 + 48 2x = 68 x = 68/2 x = 34
2x^8 x 3x^2 x -4x = -24x^11
8-(2x)=10 -(2x)=10-8 -(2x)=2 x=2/(-2) x= -1
2x * 2x * x = 4x^3
If: x^2 +2x -8 then it is (x-2)(x+4) when factored
4(x + 5) = 2x + 8 4x + 20 = 2x + 8 2x = -12 x = -6
x^3 + 8 = (x + 2)(x^2 - 2x + 4)
2X * 2X * 2X = 8X^3 2X^3 is saying 2*( X * X * X) = 2X^3
x times 2x is 2x squared or 2x2
-7 +2x = x + 8 2x - x = 7 + 8 x = 15
2X -1/3 * 2X3 - X 1/3 Order of operation; multiply first. ( multiply coefficients, add exponents ) 4X 8/3 - X 1/3 3X 7/3 =====
