Q. Solve for x. Enter the solutions from least to greatest.5x2+15x−50=0 lesser x=□ greater x=□
Write Quadratic Equation: Write down the given quadratic equation.5x2+15x−50=0
Factor Out GCF: Factor out the greatest common factor (GCF) from the quadratic equation.The GCF of 5x2, 15x, and −50 is 5.5(x2+3x−10)=0
Factor Quadratic Expression: Factor the quadratic expression inside the parentheses.We need to find two numbers that multiply to −10 and add up to 3.The numbers 5 and −2 satisfy these conditions because 5×−2=−10 and 5+(−2)=3.So, we can write the factored form as:5(x+5)(x−2)=0
Solve for x: Set each factor equal to zero and solve for x.First factor:x+5=0Subtract 5 from both sides:x=−5Second factor:x−2=0Add 2 to both sides:x=2
Write Solutions in Ascending Order: Write down the solutions in ascending order.The lesser value of x is −5, and the greater value of x is 2.
