simplify (x-5)-(x^2-1)

Solution

simplify

(x - 5) - (x^{2} - 1)

Solution

- x^{2} + x - 4

Solution steps

(x - 5) - (x^{2} - 1)

Apply rule:

(a) = a

(x - 5) = x - 5

= x - 5 - (x^{2} - 1)

Apply the distributive law:

- (a - b) = - a + b

- (x^{2} - 1) = - x^{2} + 1

= x - 5 - x^{2} + 1

Group like terms

= - x^{2} + x - 5 + 1

Add the numbers:

- 5 + 1 = - 4

= - x^{2} + x - 4
