Identify Quadratic Equation: Identify the quadratic equation to be solved.The given quadratic equation is w2−19w−20=0. We need to find two numbers that multiply to −20 and add up to −19.
Find Multiplying Numbers: Find two numbers that multiply to −20 and add up to −19. The numbers −20 and 1 have a product of −20 and a sum of −19. −20×1=−20−20+1=−19
Rewrite Using Numbers: Rewrite the quadratic equation by splitting the middle term using the numbers found in Step 2.w2−20w+w−20=0
Factor by Grouping: Factor by grouping.Group the terms to factor out common factors.(w2−20w)+(w−20)=0w(w−20)+1(w−20)=0(w−20)(w+1)=0
Solve Using Zero Product Property: Solve for w using the zero product property.Set each factor equal to zero and solve for w.w−20=0 or w+1=0w=20 or w=−1
