expand (a^2-3a)^2

Solution

expand

(a^{2} - 3 a)^{2}

Solution

a^{4} - 6 a^{3} + 9 a^{2}

Solution steps

(a^{2} - 3 a)^{2}

Apply Perfect Square Formula:

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

(a^{2} - 3 a)^{2} = (a^{2})^{2} - 2 a^{2} \cdot 3 a + (3 a)^{2}

= (a^{2})^{2} - 2 a^{2} \cdot 3 a + (3 a)^{2}

Simplify

(a^{2})^{2} - 2 a^{2} \cdot 3 a + (3 a)^{2} : a^{4} - 6 a^{3} + 9 a^{2}

= a^{4} - 6 a^{3} + 9 a^{2}
