expand-2(x+3)(x-3)+3(x^2=2x+1)

expand

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

x^{2} + 18 = 2 x + 3

Solution steps

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

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

Expand

- 2 (x + 3) (x - 3) : - 2 x^{2} + 18

= - 2 x^{2} + 18 + 3 (x^{2} = 2 x + 1)

Expand

3 (x^{2} = 2 x + 1) : 3 x^{2} = 2 x + 3

- 2 x^{2} + 18 + 3 x^{2} = 2 x + 3

Expand

- 2 x^{2} + 18 + 3 x^{2} : x^{2} + 18

x^{2} + 18 = 2 x + 3

7 x \cdot 3 y

\frac{c _{1} - 2 x}{x ( x + 2 )}

\frac{1}{2 ( - 16 a + 20 )}

\frac{x ^{2} ( x + h ) ^{2}}{h}

- 4 (- \frac{π M}{2} + 5 (2 π - 4))
