Q. Solve the quadratic by factoring.3x2+16=11x+10Answer: x=
Write Standard Form: Write the quadratic equation in standard form.To solve the quadratic equation by factoring, we need to write it in the standard form ax2+bx+c=0. We start by subtracting 11x and 10 from both sides of the equation.3x2+16−11x−10=03x2−11x+6=0
Factor Equation: Factor the quadratic equation.We need to find two numbers that multiply to give the product of a∗c (3∗6=18) and add up to b (−11).The numbers that satisfy these conditions are −9 and −2 because −9∗−2=18 and −9+(−2)=−11.
Write Factored Form: Write the factored form of the quadratic equation.Using the numbers found in Step 2, we can write the factored form of the equation as:(3x−9)(x−2)=0
Solve for x (Factor 1): Solve for x by setting each factor equal to zero.First, set the first factor equal to zero:3x−9=0Add 9 to both sides:3x=9Divide by 3:x=3
Solve for x (Factor 2): Solve for x using the second factor.Now, set the second factor equal to zero:x−2=0Add 2 to both sides:x=2
