factor x^2-7-18

factor

x^{2} - 7 - 18

(x + 5) (x - 5)

Solution steps

x^{2} - 7 - 18

Subtract the numbers:

- 7 - 18 = - 25

= x^{2} - 25

Rewrite

25

5^{2}

= x^{2} - 5^{2}

Apply Difference of Two Squares Formula:

x^{2} - y^{2} = (x + y) (x - y)

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

= (x + 5) (x - 5)

- \frac{1}{2 ^{2}}

x^{2} - 11 = 4 x

2 + ∣ 5 t - 2 ∣ = 5

4^{- 4}

(3 x - 2 y)^{3} - (5 y + 3 x)^{3}
