Show Solution

Find the roots
y1=0,y2=41
Alternative Form
y1=0,y2=0.25
Evaluate
(4y−1)(4y×9)
To find the roots of the expression,set the expression equal to 0
(4y−1)(4y×9)=0
Multiply the terms
(4y−1)×36y=0
Multiply the terms
36y(4y−1)=0
Elimination the left coefficient
y(4y−1)=0
Separate the equation into 2 possible cases
y=04y−1=0
Solve the equation
More Steps

Evaluate
4y−1=0
Move the constant to the right-hand side and change its sign
4y=0+1
Removing 0 doesn't change the value,so remove it from the expression
4y=1
Divide both sides
44y=41
Divide the numbers
y=41
y=0y=41
Solution
y1=0,y2=41
Alternative Form
y1=0,y2=0.25
