# Solve for y 2y^2=25y+13

2y2=25y+13
Subtract 25y from both sides of the equation.
2y2-25y=13
Move 13 to the left side of the equation by subtracting it from both sides.
2y2-25y-13=0
Factor by grouping.
For a polynomial of the form ax2+bx+c, rewrite the middle term as a sum of two terms whose product is a⋅c=2⋅-13=-26 and whose sum is b=-25.
Factor -25 out of -25y.
2y2-25y-13=0
Rewrite -25 as 1 plus -26
2y2+(1-26)y-13=0
Apply the distributive property.
2y2+1y-26y-13=0
Multiply y by 1.
2y2+y-26y-13=0
2y2+y-26y-13=0
Factor out the greatest common factor from each group.
Group the first two terms and the last two terms.
(2y2+y)-26y-13=0
Factor out the greatest common factor (GCF) from each group.
y(2y+1)-13(2y+1)=0
y(2y+1)-13(2y+1)=0
Factor the polynomial by factoring out the greatest common factor, 2y+1.
(2y+1)(y-13)=0
(2y+1)(y-13)=0
If any individual factor on the left side of the equation is equal to 0, the entire expression will be equal to 0.
2y+1=0
y-13=0
Set the first factor equal to 0 and solve.
Set the first factor equal to 0.
2y+1=0
Subtract 1 from both sides of the equation.
2y=-1
Divide each term by 2 and simplify.
Divide each term in 2y=-1 by 2.
2y2=-12
Cancel the common factor of 2.
Cancel the common factor.
2y2=-12
Divide y by 1.
y=-12
y=-12
Move the negative in front of the fraction.
y=-12
y=-12
y=-12
Set the next factor equal to 0 and solve.
Set the next factor equal to 0.
y-13=0
Add 13 to both sides of the equation.
y=13
y=13
The final solution is all the values that make (2y+1)(y-13)=0 true.
y=-12,13
The result can be shown in multiple forms.
Exact Form:
y=-12,13
