factor-121+81n^2

factor

- 121 + 81 n^{2}

(9 n + 11) (9 n - 11)

Solution steps

- 121 + 81 n^{2}

Write in the standard form

= 81 n^{2} - 121

Apply exponent rules

= (9 n)^{2} - 1 1^{2}

Apply Difference of Two Squares Formula:

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

(9 n)^{2} - 1 1^{2} = (9 n + 11) (9 n - 11)

= (9 n + 11) (9 n - 11)

(2 x - 1)^{2} - 7

p (t) 1800 e^{0.09 t}
