How do u solve the top one? And what do I write for the bottom one?

17. (2)

Step-by-step explanation:

-5x(x+7)(2x-3)=0

divide both sides by -5

x(x+7)(2x-3)=0

*When the product of factors equals 0, at least one factor is 0*

Set the three factors up to zero

x=0

x+7=0

2x-3=0

solve the equation

x=0

x=-7

x=3/2

this equation has three solutions from least to greatest being; -7,0,3/2

And for number 18, that equation cannot factor, that being the error.

Let me know if this was unclear, I'll be happy to further help!
