Solve -x^23=x 7 - ScanMath

Evaluate

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

Use the commutative property to reorder the terms

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

Use the commutative property to reorder the terms

- 3 x^{2} = 7 x

Move the expression to the left side

- 3 x^{2} - 7 x = 0

Factor the expression

More Steps

- x (3 x + 7) = 0

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

- x = 0 3 x + 7 = 0

Solve the equation for x

x = 0 3 x + 7 = 0

Solve the equation for x

More Steps

x = 0 x = - \frac{7}{3}

Solution

x_{1} = - \frac{7}{3}, x_{2} = 0

Alternative Form

x_{1} = - 2. \dot{3}, x_{2} = 0
