Chapter 6 - Section 6.6 - Solving Quadratic Equations by Factoring - Exercise Set: 25

Answer

x=0 and -$\frac{5}{3}$

Work Step by Step

Rewrite the equation in standard form. 3x$^2$=-5x 3x$^2$+5x=0 Factor out the GCF. x(3x+5)=0 Set each variable factor as equal to zero and then isolate the variable to find the solutions. x=0 or 3x+5=0 x=0 or 3x=-5 x=0 or x=-$\frac{5}{3}$ Enter the original equation into your graphing utility to observe that the graph crosses the x-axis at 0 and -$\frac{5}{3}$
