Answer

The solutions are 0 and$\frac{7}{2}$

Work Step by Step

x(2x-7)=0 x=0 or 2x-7=0 x=0 or 2x=7 x=0 or x=$\frac{7}{2}$ The solutions are 0 and$\frac{7}{2}$ Check Let x=0 x(2x-7)=0 0(2$\times0$-7)=0 0=0 Let x=$\frac{7}{2}$ x(2x-7)=0 $\frac{7}{2}$(2$\frac{7}{2}$-7)=0 $\frac{7}{2}$(7-7)=0 $\frac{7}{2}$$\times0$=0 0=0
