expand 2(a+b)^2+5(a+b)-3

expand

2 (a + b)^{2} + 5 (a + b) - 3

2 a^{2} + 4 ab + 2 b^{2} + 5 a + 5 b - 3

Solution steps

2 (a + b)^{2} + 5 (a + b) - 3

Expand

2 (a + b)^{2} : 2 a^{2} + 4 ab + 2 b^{2}

= 2 a^{2} + 4 ab + 2 b^{2} + 5 (a + b) - 3

Expand

5 (a + b) : 5 a + 5 b

= 2 a^{2} + 4 ab + 2 b^{2} + 5 a + 5 b - 3

4 m^{2} - 16

18 x^{2} + 3 x - 15

3 x - 7 x + 1

(- x^{2} - 5 x) - (- 6 x^{2} + 5 x + 6)

\frac{x + 1}{3} - \frac{x}{4}
