factor r^2-14r+45

factor

r^{2} - 14 r + 45

(r - 5) (r - 9)

Solution steps

r^{2} - 14 r + 45

Break the expression into groups

= (r^{2} - 5 r) + (- 9 r + 45)

Factor out

r

from

r^{2} - 5 r : r (r - 5)

Factor out

- 9

from

- 9 r + 45 : - 9 (r - 5)

= r (r - 5) - 9 (r - 5)

Factor out common term

r - 5

= (r - 5) (r - 9)

4 x^{3} \cdot 2 x^{3}

2 + 5 x - 1 > 5

e^{i \cdot \frac{π}{4}}

- 5 > x

- 2 x^{2} - x + 3 = 0
