expand (x-1)^2-16y^2

expand

(x - 1)^{2} - 16 y^{2}

x^{2} - 2 x + 1 - 16 y^{2}

Solution steps

(x - 1)^{2} - 16 y^{2}

Apply Perfect Square Formula:

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

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

= x^{2} - 2 x \cdot 1 + 1^{2} - 16 y^{2}

Simplify

x^{2} - 2 x \cdot 1 + 1^{2} : x^{2} - 2 x + 1

= x^{2} - 2 x + 1 - 16 y^{2}

4 + (- 12)

- 1 \cdot (- i)

6 (\frac{x}{6})

- 32 a + 65 a - 61

1^{\frac{- 1}{2}}
