simplify (5a^2-3a+2)-(8a^2-5a+7)

simplify

(5 a^{2} - 3 a + 2) - (8 a^{2} - 5 a + 7)

- 3 a^{2} + 2 a - 5

Solution steps

(5 a^{2} - 3 a + 2) - (8 a^{2} - 5 a + 7)

Apply rule:

(a) = a

(5 a^{2} - 3 a + 2) = 5 a^{2} - 3 a + 2

= 5 a^{2} - 3 a + 2 - (8 a^{2} - 5 a + 7)

Apply the distributive law:

- (a - b) = - a + b

- (8 a^{2} - 5 a + 7) = - 8 a^{2} + 5 a - 7

= 5 a^{2} - 3 a + 2 - 8 a^{2} + 5 a - 7

Group like terms

= 5 a^{2} - 8 a^{2} - 3 a + 5 a + 2 - 7

Add similar elements:

5 a^{2} - 8 a^{2} = - 3 a^{2}

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

Add similar elements:

- 3 a + 5 a = 2 a

= - 3 a^{2} + 2 a + 2 - 7

Subtract the numbers:

2 - 7 = - 5

= - 3 a^{2} + 2 a - 5
