factor

z^{2} + z - 42

(z - 6) (z + 7)

Solution steps

z^{2} + z - 42

Break the expression into groups

= (z^{2} - 6 z) + (7 z - 42)

Factor out

z

from

z^{2} - 6 z : z (z - 6)

Factor out

7

from

7 z - 42 : 7 (z - 6)

= z (z - 6) + 7 (z - 6)

Factor out common term

z - 6

= (z - 6) (z + 7)

7 h - 5 = 44

30 - 2 x - \frac{x ^{2}}{9} = 0

a^{20} - a^{10} + a^{5}

9 x^{2} - 12 x + 148 = 0

\frac{4}{3}
