2x(2x+5)=4x^2-3

2 x (2 x + 5) = 4 x^{2} - 3

x = - \frac{3}{10}

Decimal Notation

x = - 0.3

Solution steps

2 x (2 x + 5) = 4 x^{2} - 3

Expand

2 x (2 x + 5) : 4 x^{2} + 10 x

4 x^{2} + 10 x = 4 x^{2} - 3

Move

4 x^{2}

to the left side

10 x = - 3

Divide both sides by

10

x = - \frac{3}{10}

\frac{75}{0.15} = \frac{0.15 \cdot + x}{0.15}

a, 5 a - 2 b = 3

x, 3 y - 2 x = - 9

x, 3 x - 6 y = - 15

\frac{7 x}{15 - 1} = 22
