factor y^2-15y+56

factor

y^{2} - 15 y + 56

(y - 7) (y - 8)

Solution steps

y^{2} - 15 y + 56

Break the expression into groups

= (y^{2} - 7 y) + (- 8 y + 56)

Factor out

y

from

y^{2} - 7 y : y (y - 7)

Factor out

- 8

from

- 8 y + 56 : - 8 (y - 7)

= y (y - 7) - 8 (y - 7)

Factor out common term

y - 7

= (y - 7) (y - 8)

\frac{sin ( 3 x )}{sin ( x )} - \frac{cos ( 3 x )}{cos ( x )}
