simplify 3(7p-3q+9)

Solution

simplify

3 (7 p - 3 q + 9)

21 p - 9 q + 27

Solution steps

3 (7 p - 3 q + 9)

Apply the distributive law:

m (a + b + c) = ma + mb + m c

3 (7 p - 3 q + 9) = 3 \cdot 7 p + 3 (- 3 q) + 3 \cdot 9

= 3 \cdot 7 p + 3 (- 3 q) + 3 \cdot 9

Simplify

3 \cdot 7 p + 3 (- 3 q) + 3 \cdot 9 : 21 p - 9 q + 27

= 21 p - 9 q + 27

\frac{x ^{2} + 7 x + 6}{x ^{2} - 5 x - 6}

(- 2) (- 2) (- 2) (- 2)

11 - (- 1)

(6 + 8 i) (4 + 2 i)

(- 5 x^{2} + 7 x + 2) - (- 5 x^{2} - 7 x + 2)
