x^2/x +2=4/x +2 (x^2/x)-(4/x)=0 (x^2-4)/x=0 x^2-4=0 (x+2)(x-2)=0 x=±2
what is equivalent to (x plus 4)2
x^(3) + x^(2) + 4x + 4 Factirise x^(2)(x + 1) + 4(x+1) => (X^(2) + 4)(x + 1) = > (x^(2) + 2^(2))(x + 1) NB ; REmember two squared terms with a positive (+) between then does NOT factor.
4x^2 + 32x + 64 = 4(x^2 + 8x + 16) = 4(x + 4)^2 = 4(x + 4)(x + 4)
equals x+2 PROVIDED x is not -2. If x is -2, the ratio is not defined.
x/(x + 4) = 4/(x + 4) + 2 (x - 4)/(x + 4) = 2 x - 4 = 2x + 8 -x = 12 x = -12
x+x+2+x+4+x+6=42(x+x+x+x)+(2+4+6)=424x+12=424x=30x=15/2or 7 and 1/2

(x^2-4) (x^2+6x+8) __________ x _________ which is (x^2+2x-8) (x^2+4x+4) (x+2)(x-2) (x^2+4x+2x+8) ___________ x _____________ which is (x^2+4x-2x-8) (x^2+2x+2x+4) (x+2)(x-2) x(x+4)+2(x+4) ___________ x ____________ which is x(x+4)-2(x+4) x(x+2)+2(x+2) (x+2)(x-2) (x+2)(x+4) ________ x _________ which is 1 as all the terms in the num & den cancel (x-2)(x+4) (x+2)(x+2)
(x+4)(x+4), or (x+4)^2.
x^2/x +2=4/x +2 (x^2/x)-(4/x)=0 (x^2-4)/x=0 x^2-4=0 (x+2)(x-2)=0 x=±2
If: x + 2/2 + x + 5/7 = 4 Then: x = 8/7
The equation 5X plus 4 X-2 -2X 2 X-1 plus3 X plus 2 equals to 2. This is college math.
(x+2)(x+2) or (x+2)^2
