Solve 7u=u^24 - ScanMath

Evaluate

7 u = u^{2} \times 4

Use the commutative property to reorder the terms

7 u = 4 u^{2}

Swap the sides

4 u^{2} = 7 u

Move the expression to the left side

4 u^{2} - 7 u = 0

Factor the expression

More Steps

u (4 u - 7) = 0

When the product of factors equals 0,at least one factor is 0

4 u - 7 = 0 u = 0

Solve the equation for u

More Steps

u = \frac{7}{4} u = 0

Solution

u_{1} = 0, u_{2} = \frac{7}{4}

Alternative Form

u_{1} = 0, u_{2} = 1.75
