simplify (3x^2-5x)-(-4+x^2+x)

simplify

(3 x^{2} - 5 x) - (- 4 + x^{2} + x)

2 x^{2} - 6 x + 4

Solution steps

(3 x^{2} - 5 x) - (- 4 + x^{2} + x)

Apply rule:

(a) = a

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

= 3 x^{2} - 5 x - (- 4 + x^{2} + x)

Apply the distributive law:

- (- a + b) = a - b

- (- 4 + x^{2} + x) = 4 - x^{2} - x

= 3 x^{2} - 5 x + 4 - x^{2} - x

Group like terms

= 3 x^{2} - x^{2} - 5 x - x + 4

Add similar elements:

3 x^{2} - x^{2} = 2 x^{2}

= 2 x^{2} - 5 x - x + 4

Add similar elements:

- 5 x - x = - 6 x

= 2 x^{2} - 6 x + 4

1800 (1.004)^{5}

\frac{( x ^{2} + 3 x + 2 )}{x ^{2} - x - 2}

\frac{5}{6} - 4

254 - 424
