Q. Solve for x. Enter the solutions from least to greatest.x2−5x−14=0 lesser x=□ greater x=□
Identify quadratic equation: Identify the quadratic equation to be solved.The given quadratic equation is x2−5x−14=0. We need to find two numbers that multiply to −14 and add up to −5.
Factor the quadratic equation: Factor the quadratic equation.To factor x2−5x−14, we look for two numbers that multiply to −14 and add to −5. The numbers −7 and 2 satisfy these conditions because −7×2=−14 and −7+2=−5.So, we can write the equation as (x−7)(x+2)=0.
Solve for x: Solve for x using the zero product property.If (x−7)(x+2)=0, then either x−7=0 or x+2=0.Solving x−7=0 gives us x=7.Solving x+2=0 gives us x=−2.
Write the solutions: Write the solutions in ascending order.The lesser value of x is −2, and the greater value of x is 7.
