expand 9(a+x)^2-12(a+x)+4

expand

9 (a + x)^{2} - 12 (a + x) + 4

9 a^{2} + 18 a x + 9 x^{2} - 12 a - 12 x + 4

Solution steps

9 (a + x)^{2} - 12 (a + x) + 4

Expand

9 (a + x)^{2} : 9 a^{2} + 18 a x + 9 x^{2}

= 9 a^{2} + 18 a x + 9 x^{2} - 12 (a + x) + 4

Expand

- 12 (a + x) : - 12 a - 12 x

= 9 a^{2} + 18 a x + 9 x^{2} - 12 a - 12 x + 4
