Q. Solve for m. m2+20m+19=0Write each solution as an integer, proper fraction, or improper fraction in simplest form. If there are multiple solutions, separate them with commas. m= ____
Identify quadratic equation: Identify the quadratic equation to solve.The given quadratic equation is m2+20m+19=0. We need to find two numbers that multiply to 19 and add up to 20.
Find multiplying numbers: Find two numbers that multiply to 19 and add up to 20. The numbers 1 and 19 multiply to 19 (1×19=19) and add up to 20 (1+19=20).
Rewrite quadratic equation: Rewrite the quadratic equation by splitting the middle term using the numbers found in Step 2.m2+20m+19=0 can be rewritten asm2+19m+1m+19=0.
Factor by grouping: Factor by grouping.Group the terms to factor by common terms:(m2+19m)+(1m+19)=0m(m+19)+1(m+19)=0(m+1)(m+19)=0
Solve for m: Solve for m using the zero product property.Set each factor equal to zero and solve for m:m+1=0 or m+19=0m=−1 or m=−19
