Q. Solve for x. Enter the solutions from least to greatest.x2+x−30=0 lesser x=□ greater x=□
Identify the quadratic equation: Identify the quadratic equation to be solved.We have the quadratic equation x2+x−30=0. We need to find two numbers that multiply to −30 and add up to 1, which are the coefficients of the x2 and x terms, respectively.
Factor the quadratic equation: Factor the quadratic equation.The two numbers that multiply to −30 and add up to 1 are 6 and −5 because 6×(−5)=−30 and 6+(−5)=1. Therefore, we can factor the quadratic equation as follows:x2+x−30=(x+6)(x−5)=0
Solve for x: Solve for x by setting each factor equal to zero.First, set the first factor equal to zero:x+6=0Subtract 6 from both sides to solve for x:x=−6Next, set the second factor equal to zero:x−5=0Add 5 to both sides to solve for x:x=5We have found two solutions: x=−6 and x=5.
Write the solutions: Write the solutions in ascending order.The lesser value of x is −6, and the greater value of x is 5.
