factor m^2-4m-5

factor

m^{2} - 4 m - 5

(m + 1) (m - 5)

Solution steps

m^{2} - 4 m - 5

Break the expression into groups

= (m^{2} + m) + (- 5 m - 5)

Factor out

m

from

m^{2} + m : m (m + 1)

Factor out

- 5

from

- 5 m - 5 : - 5 (m + 1)

= m (m + 1) - 5 (m + 1)

Factor out common term

m + 1

= (m + 1) (m - 5)

x^{2} + 8 x - 84 = 0

\frac{1}{27} y^{9} - \frac{27}{1000} x^{12}

x^{2} + 5 x \leq 6

(\frac{7}{4})^{- 2}

x^{4} + 5 x^{2} - 36
