simplify (x^2+9)-(x-9)

Solution

simplify

(x^{2} + 9) - (x - 9)

Solution

x^{2} - x + 18

Solution steps

(x^{2} + 9) - (x - 9)

Apply rule:

(a) = a

(x^{2} + 9) = x^{2} + 9

= x^{2} + 9 - (x - 9)

Apply the distributive law:

- (a - b) = - a + b

- (x - 9) = - x + 9

= x^{2} + 9 - x + 9

Group like terms

= x^{2} - x + 9 + 9

Add the numbers:

9 + 9 = 18

= x^{2} - x + 18
