expand ,(3x^2-5x+1)-(7x^2-2x+4)

expand

(3 x^{2} - 5 x + 1) - (7 x^{2} - 2 x + 4)

- 4 x^{2} - 3 x - 3

Solution steps

(3 x^{2} - 5 x + 1) - (7 x^{2} - 2 x + 4)

Apply rule:

(a) = a

(3 x^{2} - 5 x + 1) = 3 x^{2} - 5 x + 1

= 3 x^{2} - 5 x + 1 - (7 x^{2} - 2 x + 4)

Expand

- (7 x^{2} - 2 x + 4) : - 7 x^{2} + 2 x - 4

= 3 x^{2} - 5 x + 1 - 7 x^{2} + 2 x - 4

Simplify

3 x^{2} - 5 x + 1 - 7 x^{2} + 2 x - 4 : - 4 x^{2} - 3 x - 3

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

\frac{( s + 0.4 )}{s ( s + 0.8 )}

(2 y - 3 x) d x - x d y

π (80 ln (6) - \frac{125}{6})

\frac{40000 ( 20 s + 5 )}{s ( 20 s + 1 )}

(\frac{3}{b} + 4 e)^{3}
