factor 4ax+4bx-ay-15a-by-15b

factor

4 a x + 4 b x - a y - 15 a - b y - 15 b

(a + b) (4 x - 15 - y)

Solution steps

4 a x + 4 b x - a y - 15 a - b y - 15 b

Factor out common term

4 x

= 4 x (a + b) - a y - 15 a - b y - 15 b

Factor out common term

a

= 4 x (a + b) - a (y + 15) - b y - 15 b

Factor out common term

b

= 4 x (a + b) - a (15 + y) - b (y + 15)

Factor out common term

(15 + y)

= 4 x (a + b) - (15 + y) (a + b)

Factor out common term

(a + b)

= (a + b) (4 x - (15 + y))

Expand

4 x - (y + 15) : 4 x - 15 - y

= (a + b) (4 x - y - 15)

- t^{2} - 10 + 9

1 + x^{2} (x^{2} + 2)

7 a x - 7 b x - 3 a y + 3 b y

1 - x - x yz + yz

1 - (5 x)
