Solve x^2 7=4x - ScanMath

Evaluate

x^{2} \times 7 = 4 x

Use the commutative property to reorder the terms

7 x^{2} = 4 x

Move the expression to the left side

7 x^{2} - 4 x = 0

Factor the expression

More Steps

x (7 x - 4) = 0

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

7 x - 4 = 0 x = 0

Solve the equation for x

More Steps

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

Solution

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

Alternative Form

x_{1} = 0, x_{2} = 0. \dot{5} 7142 \dot{8}
