simplify 1/4 (4f-8)

Solution

simplify

\frac{1}{4} (4 f - 8)

f - 2

Solution steps

\frac{1}{4} (4 f - 8)

Apply the distributive law:

a (b - c) = ab - a c

\frac{1}{4} (4 f - 8) = \frac{1}{4} \cdot 4 f - \frac{1}{4} \cdot 8

= \frac{1}{4} \cdot 4 f - \frac{1}{4} \cdot 8

Simplify

\frac{1}{4} \cdot 4 f - \frac{1}{4} \cdot 8 : f - 2

= f - 2

- \frac{1}{2} (8)

(3 a + 7)^{2} - 5 a (a - 4)

2 x + 5 y - 3 y

(4^{- 1} + 4^{0}) - (9^{- 1} + 9^{0})
