expand (2x^2-9x+2)-(9x^2-4x=4)

expand

(2 x^{2} - 9 x + 2) - (9 x^{2} - 4 x = 4)

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

Solution steps

(2 x^{2} - 9 x + 2) - (9 x^{2} - 4 x = 4)

= (2 x^{2} - 9 x + 2) - (9 x^{2} - 4 \cdot 4 = x)

- (9 x^{2} - 4 x = 4) : - 9 x^{2} + 4 x = 4

(2 x^{2} - 9 x + 2) - 9 x^{2} + 4 x = 4

Expand

(2 x^{2} - 9 x + 2) - 9 x^{2} + 4 x : - 7 x^{2} - 5 x + 2

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

\frac{( 3 - s )}{2 ( 9 + s ^{2} )}
