simplify (5x^2+7)-(3x-2)

Solution

simplify

(5 x^{2} + 7) - (3 x - 2)

Solution

5 x^{2} - 3 x + 9

Solution steps

(5 x^{2} + 7) - (3 x - 2)

Apply rule:

(a) = a

(5 x^{2} + 7) = 5 x^{2} + 7

= 5 x^{2} + 7 - (3 x - 2)

Apply the distributive law:

- (a - b) = - a + b

- (3 x - 2) = - 3 x + 2

= 5 x^{2} + 7 - 3 x + 2

Group like terms

= 5 x^{2} - 3 x + 7 + 2

Add the numbers:

7 + 2 = 9

= 5 x^{2} - 3 x + 9
