STEP 1 : Equation at the end of step 1 0 - 7n • (n - 7) = 0 STEP 2 : Equation at the end of step 2 -7n • (n - 7) = 0 STEP 3 : Theory - Roots of a product 3.1 A product of several terms equals zero. When a product of two or more terms equals zero, then at least one of the terms must be zero. We shall now solve each term = 0 separately In other words, we are going to solve as many equations as there are terms in the product Any solution of term = 0 solves product = 0 as well. Solving a Single Variable Equation: 3.2 Solve : -7n = 0 Multiply both sides of the equation by (-1) : 7n = 0
Divide both sides of the equation by 7: n = 0 Solving a Single Variable Equation: 3.3 Solve : n-7 = 0 Add 7 to both sides of the equation : n = 7
This is what i got! if i’m wrong i’m so sorry but i tried. have a amazing day☺️☺️
