Question

Doar punctul b ex 11 pls​

Answer 1

$\frac{2}{5} ax + ax ^{2} - \frac{1}{10}ax - 0lax + a ^{2} - \frac{2}{3} a ^{2} + ax$

$a \times ( \frac{2}{5} x + x ^{2} - \frac{1}{10} x0lx + a - \frac{2}{3} a + x)$

$a \times ( \frac{2}{5} x + x ^{2} - \frac{1}{10} x + 0 + a - \frac{2}{3}a + x)$

$a \times ( \frac{13}{10} x + x^{2} + \frac{1}{3} a)$
