simplify (9x^2+10x+4)-(9x^2+5x-1)

simplify

(9 x^{2} + 10 x + 4) - (9 x^{2} + 5 x - 1)

5 x + 5

Solution steps

(9 x^{2} + 10 x + 4) - (9 x^{2} + 5 x - 1)

Apply rule:

(a) = a

(9 x^{2} + 10 x + 4) = 9 x^{2} + 10 x + 4

= 9 x^{2} + 10 x + 4 - (9 x^{2} + 5 x - 1)

Apply the distributive law:

- (a + b) = - a - b

- (9 x^{2} + 5 x - 1) = - 9 x^{2} - 5 x + 1

= 9 x^{2} + 10 x + 4 - 9 x^{2} - 5 x + 1

Group like terms

= 9 x^{2} - 9 x^{2} + 10 x - 5 x + 4 + 1

Add similar elements:

9 x^{2} - 9 x^{2} = 0

= 10 x - 5 x + 4 + 1

Add similar elements:

10 x - 5 x = 5 x

= 5 x + 4 + 1

Add the numbers:

4 + 1 = 5

= 5 x + 5
