5y^2 - 2 = 3y

y= -2/5 and y=1

Step-by-step explanation:

Start by transforming the equation to your liking:

Now we have to factor! To do this we have to find common numbers. Do this by multiplying -2 and 5 to get -10. Now think about which two numbers add multiply to be -10 but also add up to be -3 (I got this number from the middle of the equation). The two numbers you should've got are -5 and 2.

Now substitute those two number in place of the middle term, which is -3y like so:

Now solve the equation in pieces... find the greatest common factor from and the greatest common factor from . The two common factors for both of those are 5y and 2. Your equation should now look like this:

+

The two greatest common factors become into one group and the other equation that they have in common (y-1) is it's own equation:

Now equal both of the equations to 0 and solve for y to get both of the values of y.
