I'm not sure how to solve
2y(1+y)=4
2y(1+y)=4
-
Divide both sides by 2 to get:
y(1 + y) = 2
Distribute y into 1 + y:
y² + y = 2
Then, convert y² + y = 2 into standard form:
y² + y - 2 = 0
Factor:
(y - 1)(y + 2) = 0
Finally, set each factor to zero and solve for y.
y - 1 = 0 and y + 2 = 0
y = {1,-2}
I hope this helps!

2y(1+y)=4
2y + 2y^2 = 4 put the polynomials in order
2y^2 + 2y = 4
factor to = 0
2y^2 + 2y - 4 = 0
(first, outer, inner, last)
(2y - 2)(y + 2) = 2y^2 + 4y - 2y - 4 which equals 2y^2 + 2y - 4 = 0
2y-2=0
2y=2
y=1
y+2=0
y=-2
{1, -2}

2y(1+y)=4
First, Remove 2 from the equation.
2/2y(1+y) = 4/2
y(1+y) = 2
Then Remove 1 from equation.
y(1-1+y) = 2-1
y =
/check you answer =
2 * 1 ( 1+ 1) =
4!!

2y ( 1+y) = 4
=> 2y + 2y ^2 = 4
=> 2y^2 + 2y - 4 = 0
=> 2y^2 - 2y + 4y - 4 = 0
=> 2y( y - 1) + 4( y - 1) = 0
=> ( y- 1)( 2y + 4) = 0
This is the factoring and
further either y - 1 = 0 or 2y +4 = 0
=> either y = 1 or 2y = - 4
=> either y = 1 or y = - 4/2 = -2
so thats the value of y . Hope u find it easy!!!
=> 2y + 2y ^2 = 4

=> ( y- 1)( 2y + 4) = 0

You can just distribute so then after it should look like this :
2y+y=4
Then add the y's
3y=4
then divide 4/3
so y=4/3 or 1 1/3
2y+y=4
Then add the y's
3y=4
then divide 4/3
so y=4/3 or 1 1/3

2y(1+y)=4 distribute
2y + 2y^2=4 set it equal to zero to get a quadratic
2y^2+2y-4=0 factor
(2y-2)(y+2) solve for y
y=1,y=-2
2y + 2y^2=4 set it equal to zero to get a quadratic
2y^2+2y-4=0 factor
(2y-2)(y+2) solve for y
y=1,y=-2

Ok.
What's the Question? Idontgetit.
I'm actually good at algebra.
