Q. Solve the quadratic by factoring.x2+4x−15=6xAnswer: x=
Move Terms, Set Equal: First, we need to move all terms to one side of the equation to set it equal to zero.x2+4x−15=6xSubtract 6x from both sides to get:x2+4x−6x−15=0Combine like terms:x2−2x−15=0
Factor Quadratic Equation: Now, we need to factor the quadratic equationx2−2x−15. We are looking for two numbers that multiply to −15 and add up to −2. The numbers −5 and 3 satisfy these conditions because: −5×3=−15−5+3=−2 So we can write the factored form as: (x−5)(x+3)=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−5=0 or x+3=0Solving each equation gives us:x=5 or x=−3
