expand 4(x-1)(x-5)

Solution

expand

4 (x - 1) (x - 5)

Solution

4 x^{2} - 24 x + 20

Solution steps

4 (x - 1) (x - 5)

Expand

4 (x - 1) (x - 5) : 4 (x^{2} - 6 x + 5)

= 4 (x^{2} - 6 x + 5)

Apply the distributive law:

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

4 (x^{2} - 6 x + 5) = 4 x^{2} + 4 (- 6 x) + 4 \cdot 5

= 4 x^{2} + 4 (- 6 x) + 4 \cdot 5

Simplify

4 x^{2} + 4 (- 6 x) + 4 \cdot 5 : 4 x^{2} - 24 x + 20

= 4 x^{2} - 24 x + 20
