Solution steps

b^{2} - 1

Rewrite

1

as

1^{2}

= b^{2} - 1^{2}

Apply Difference of Two Squares Formula:

x^{2} - y^{2} = (x + y) (x - y)

b^{2} - 1^{2} = (b + 1) (b - 1)

= (b + 1) (b - 1)

Popular Examples

z^{2} + z - 6 = 0

3x+4=6(5x-5)+88

3 x + 4 = 6 (5 x - 5) + 88

3 6^{2} + b^{2} = 8 5^{2}
