Q. Solve for all values of x x by factoring.\newlinex26=2 x^{2}-6=-2 \newlineAnswer: x= x=
  1. Isolate x2x^2 term: Write down the equation and add 66 to both sides to isolate the x2x^2 term.\newlinex26=2x^2 - 6 = -2\newlinex26+6=2+6x^2 - 6 + 6 = -2 + 6\newlinex2=4x^2 = 4
  2. Factor the equation: Factor the equation x2=4x^2 = 4.\newlineWe recognize that 44 is a perfect square, so we can write the equation as:\newlinex2=22x^2 = 2^2\newlineThis implies that xx could be either positive or negative 22, since both (2)2(2)^2 and (2)2(-2)^2 equal 44.
  3. Write down solutions for x: Write down the two possible solutions for x.\newlinex=2x = 2 or x=2x = -2
