Q. Solve for z.29z2−20z=0Write each solution as an integer, proper fraction, or improper fraction in simplest form. If there are multiple solutions, separate them with commas.z=____
Factor GCF: Factor out the greatest common factor (GCF) from the equation 29z2−20z=0. The GCF of 29z2 and 20z is z. Factor out z from each term. z(29z−20)=0
Set Equal Zero: Set each factor equal to zero and solve for z.First, set z equal to zero:z=0This is one solution.
Solve for z: Now set the other factor equal to zero and solve for z:29z−20=0Add 20 to both sides to isolate the term with z.29z=20Divide both sides by 29 to solve for z.z=2920This is the second solution.
Write Solutions: Write the values of z. We have two solutions from the factored equation z(29z−20)=0. The equation will be true if either z=0 or 29z−20=0. z=0, 2920
