Q. Solve the quadratic by factoring.x2+x−56=−x+7Answer: x=
Move Terms, Combine Like Terms: First, we need to move all terms to one side of the equation to set it equal to zero.x2+x−56+x−7=0Combine like terms.x2+2x−63=0
Factor Quadratic Equation: Now, we need to factor the quadratic equationx2+2x−63. We are looking for two numbers that multiply to −63 and add up to 2. The numbers 9 and −7 work because 9×−7=−63 and 9+(−7)=2. So, we can write the factored form as (x+9)(x−7)=0.
Apply Zero Product Property: Next, we apply the zero product property, which states that if a product of two factors is zero, then at least one of the factors must be zero.So, we set each factor equal to zero and solve for x.x+9=0 or x−7=0
Solve for x in First Equation: Solving the first equation x+9=0 for x gives us:x=−9
Solve for x in Second Equation: Solving the second equation x−7=0 for x gives us: x=7
