a^{2} + 3 a - 4

(a - 1) (a + 4)

Solution steps

a^{2} + 3 a - 4

Break the expression into groups

= (a^{2} - a) + (4 a - 4)

Factor out

a

from

a^{2} - a : a (a - 1)

Factor out

4

from

4 a - 4 : 4 (a - 1)

= a (a - 1) + 4 (a - 1)

a - 1

= (a - 1) (a + 4)

9 0^{2} + 9 0^{2} = c^{2}

3 x y + 2 x^{2}

x^{2} + 18 x = 6

(\frac{3 x ^{7} y ^{9}}{5 x ^{5} y ^{2}})^{- 4}

x^{2} + 6 x + 5 \leq 0
