simplify (-6s^2+12s-8)-(3s^2+8s-6)

simplify

(- 6 s^{2} + 12 s - 8) - (3 s^{2} + 8 s - 6)

- 9 s^{2} + 4 s - 2

Solution steps

(- 6 s^{2} + 12 s - 8) - (3 s^{2} + 8 s - 6)

Apply rule:

(a) = a

(- 6 s^{2} + 12 s - 8) = - 6 s^{2} + 12 s - 8

= - 6 s^{2} + 12 s - 8 - (3 s^{2} + 8 s - 6)

Apply the distributive law:

- (a + b) = - a - b

- (3 s^{2} + 8 s - 6) = - 3 s^{2} - 8 s + 6

= - 6 s^{2} + 12 s - 8 - 3 s^{2} - 8 s + 6

Group like terms

= - 6 s^{2} - 3 s^{2} + 12 s - 8 s - 8 + 6

Add similar elements:

- 6 s^{2} - 3 s^{2} = - 9 s^{2}

= - 9 s^{2} + 12 s - 8 s - 8 + 6

Add similar elements:

12 s - 8 s = 4 s

= - 9 s^{2} + 4 s - 8 + 6

Add the numbers:

- 8 + 6 = - 2

= - 9 s^{2} + 4 s - 2

\frac{3 + 4 i}{7 - i}
