factor

a^{2} b^{2} - 144

(ab + 12) (ab - 12)

Solution steps

a^{2} b^{2} - 144

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

144 = 1 2^{2}

= (ab)^{2} - 1 2^{2}

Apply Difference of Two Squares Formula:

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

(ab)^{2} - 1 2^{2} = (ab + 12) (ab - 12)

= (ab + 12) (ab - 12)

- 8.3 \div 0.25

- \frac{7}{8} + \frac{9}{8}

\frac{- 3. 1 ^{3} + 27}{- 3.1 + 3}
