4 x^{2} = 49

x = \frac{7}{2}, x = - \frac{7}{2}

Decimal Notation

x = 3.5, x = - 3.5

Solution steps

4 x^{2} = 49

Divide both sides by

4

x^{2} = \frac{49}{4}

For

x^{2} = f (a)

the solutions are

x = f (a), - f (a)

x = \frac{49}{4}, x = - \frac{49}{4}

\frac{49}{4} = \frac{7}{2}

- \frac{49}{4} = - \frac{7}{2}

x = \frac{7}{2}, x = - \frac{7}{2}

2000 = 37

x^{2} + 3 x - 5 x - 15 = 0

19 - 2 x > 13

16.2 \cdot 3.51 - \frac{1}{2} \cdot 9.81 \cdot 3.5 1^{2}

2 x^{2} + 3 x - 2
