Use the quadratic formula to solve 4y^2+ 8y +7 =4

Step-by-step explanation:

The Quadratic formula is:

Given the equation , you need to subtract 4 from both sides:

Now you can identify that:

Then you can substitute these values into the Quadratic formula. Therefore, you get these solutions:

The solutions are y=-1/2 and y=-3/2

Step-by-step explanation:

Ok, for this problem we need to use the quadratic formula:

For

The values of x which are the solutions of the equation:

In this case your variable is y, so:

So, a=4, b=8 and c=3

and

The solutions are
