7 x^{2} = - 4 x

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

Decimal Notation

x = 0, x = - 0.57142 \dots

Solution steps

7 x^{2} = - 4 x

Move

4 x

to the left side

7 x^{2} + 4 x = 0

Factor

7 x^{2} + 4 x : x (7 x + 4)

x (7 x + 4) = 0

Using the Zero Factor Principle:

ab = 0

then

a = 0

b = 0

x = 0 or 7 x + 4 = 0

Solve

7 x + 4 = 0 : x = - \frac{4}{7}

The solutions to the quadratic equation are:

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

2 λ^{2} - 1 = 0

x, z = 1 + (x - 1)^{2} + 4 y^{2}

m^{2} - 5 m - 14 = 0

- 10000 x^{2} + 4000 x + 9000 = 0

6 + 4 (4.5 - x) = 4 + x^{2}
