Prime factorization of

50 : 2 \cdot 5^{2}

= 3 2 \cdot 5^{2}

Apply radical rule:

ab = a b, a \geq 0, b \geq 0

2 \cdot 5^{2} = 2 5^{2}

= 32 5^{2}

Apply radical rule:

a^{2} = a, a \geq 0

5^{2} = 5

= 32 \cdot 5

Multiply the numbers:

3 \cdot 5 = 15

= 152

3 x - 1 = 11

\frac{9}{40} + \frac{1}{8} - \frac{7}{15}

121 - x^{2}

5 (1 - x)^{2} - 6 (x^{2} - 3 x - 7) = x (x - 3) - 2 x (x + 5) - 2
