factor x^2+x-42

factor

x^{2} + x - 42

(x - 6) (x + 7)

Solution steps

x^{2} + x - 42

Break the expression into groups

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

Factor out

x

from

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

Factor out

7

from

7 x - 42 : 7 (x - 6)

= x (x - 6) + 7 (x - 6)

Factor out common term

x - 6

= (x - 6) (x + 7)

(\frac{a ^{2}}{4})^{3}

x^{3} + 15 x \geq - 8 x^{2}

f = 3 (- 1)^{2} - (- 1) - 1

∣ 5 x - 17 ∣ = - 13

2 (5 + z) = 16
