Q. Solve for all values of x by factoring.x2−6=−2Answer: x=
Isolate x2 term: Write down the equation and add 6 to both sides to isolate the x2 term.x2−6=−2x2−6+6=−2+6x2=4
Factor the equation: Factor the equation x2=4.We recognize that 4 is a perfect square, so we can write the equation as:x2=22This implies that x could be either positive or negative 2, since both (2)2 and (−2)2 equal 4.
Write down solutions for x: Write down the two possible solutions for x.x=2 or x=−2
