could someone help me understand this problem?

Question

Solve the following equation for the indicated variable:


(7y-8)(2y+7)=0

 

 

Hint: This equation is already in factored form, so use the Zero-Factor Property to set each of the factors equal to 0.

Answer 1

Hi Jared,

 

When you multiply a term by zero, the answer is zero.

 

So set each of the factors to be equal to zero and solve for the variable.

 

7y - 8 = 0

7y = 8

y = 8/7

 

Now you can do the same for the second factor.

 

Have fun.
