expand (4a-1)^2

Solution

expand

(4 a - 1)^{2}

Solution

16 a^{2} - 8 a + 1

Solution steps

(4 a - 1)^{2}

Apply Perfect Square Formula:

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

(4 a - 1)^{2} = (4 a)^{2} - 2 \cdot 4 a \cdot 1 + 1^{2}

= (4 a)^{2} - 2 \cdot 4 a \cdot 1 + 1^{2}

Simplify

(4 a)^{2} - 2 \cdot 4 a \cdot 1 + 1^{2} : 16 a^{2} - 8 a + 1

= 16 a^{2} - 8 a + 1
