factor

a^{2} - 15 a + 56

(a - 7) (a - 8)

Solution steps

a^{2} - 15 a + 56

Break the expression into groups

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

Factor out

a

from

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

Factor out

- 8

from

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

= a (a - 7) - 8 (a - 7)

Factor out common term

a - 7

= (a - 7) (a - 8)

- x^{2} - 2 x = 1

25 \leq 4 + 3 y

\frac{3}{\frac{π}{2}}

(2 x - 3) (x - 1)^{2} (x - 3) \geq 0

- 3 x = 15
