expand 3(x-1)(x-3)

Solution

expand

3 (x - 1) (x - 3)

Solution

3 x^{2} - 12 x + 9

Solution steps

3 (x - 1) (x - 3)

Expand

3 (x - 1) (x - 3) : 3 (x^{2} - 4 x + 3)

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

Apply the distributive law:

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

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

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

Simplify

3 x^{2} + 3 (- 4 x) + 3 \cdot 3 : 3 x^{2} - 12 x + 9

= 3 x^{2} - 12 x + 9
