Solve 4x 7 - x = 3(x^2) 1

Evaluate

4 x \times 7 - x = 3 x^{2} \times 1

Simplify

More Steps

27 x = 3 x^{2} \times 1

Multiply the terms

27 x = 3 x^{2}

Swap the sides

3 x^{2} = 27 x

Move the expression to the left side

3 x^{2} - 27 x = 0

Factor the expression

More Steps

3 x (x - 9) = 0

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

x - 9 = 0 3 x = 0

Solve the equation for x

More Steps

x = 9 3 x = 0

Solve the equation for x

x = 9 x = 0

Solution

x_{1} = 0, x_{2} = 9
