Q. Solve for all values of x by factoring.x2−9x+3=−5Answer: x=
Rewrite Equation: Rewrite the equation to set it equal to zero.We start by adding 5 to both sides of the equation to set the right side to zero.x2−9x+3+5=0x2−9x+8=0
Factor Quadratic: Factor the quadratic equation.We need to find two numbers that multiply to 8 (the constant term) and add up to −9 (the coefficient of the x term).The numbers that satisfy these conditions are −1 and −8 because:−1×−8=8−1+(−8)=−9So we can factor the quadratic as:(x−1)(x−8)=0
Solve for x: Solve for x by setting each factor equal to zero.If (x−1)(x−8)=0, then either (x−1)=0 or (x−8)=0.Solving each equation for x gives us:x−1=0 => x=1x−8=0 => x=8
