Simplifying (-7x)(5x2 + y) = 0 Remove parenthesis around (-7x) -7x(5x2 + y) = 0 (5x2 * -7x + y * -7x) = 0 Reorder the terms: (-7xy + -35x3) = 0 (-7xy + -35x3) = 0 Solving -7xy + -35x3 = 0 Solving for variable 'x'. Factor out the Greatest Common Factor (GCF), '-7x'. -7x(y + 5x2) = 0 Ignore the factor -7.Subproblem 1
Set the factor 'x' equal to zero and attempt to solve: Simplifying x = 0 Solving x = 0 Move all terms containing x to the left, all other terms to the right. Simplifying x = 0Subproblem 2
Set the factor '(y + 5x2)' equal to zero and attempt to solve: Simplifying y + 5x2 = 0 Reorder the terms: 5x2 + y = 0 Solving 5x2 + y = 0 Move all terms containing x to the left, all other terms to the right. Add '-1y' to each side of the equation. 5x2 + y + -1y = 0 + -1y Combine like terms: y + -1y = 0 5x2 + 0 = 0 + -1y 5x2 = 0 + -1y Remove the zero: 5x2 = -1y Divide each side by '5'. x2 = -0.2y Simplifying x2 = -0.2y The solution to this equation could not be determined. This subproblem is being ignored because a solution could not be determined.Solution
