${(a + b^{2} - c^{3})}^{2}$

Step 1

Rewrite ${(a + b^{2} - c^{3})}^{2}$ as $(a + b^{2} - c^{3}) (a + b^{2} - c^{3})$ .

$(a + b^{2} - c^{3}) (a + b^{2} - c^{3})$

Step 2

Expand $(a + b^{2} - c^{3}) (a + b^{2} - c^{3})$ by multiplying each term in the first expression by each term in the second expression.

$a \cdot a + a b^{2} + a (- c^{3}) + b^{2} a + b^{2} b^{2} + b^{2} (- c^{3}) - c^{3} a - c^{3} b^{2} - c^{3} (- c^{3})$
