Разложите на множители
t²-p²
c²d²-1
25x²-144y²
2d²-72c²

Answer 1

Объяснение:

$t {}^{2} - p {}^{2} = (t - p)(t + p)$

$c {}^{2} d {}^{2} - 1 = (cd - 1)(cd + 1)$

$25x {}^{2} - 144y { }^{2} = (5x - 12y)(5x + 12y)$

$2d {}^{2} - 72c {}^{2} =2\left(d^{2}-36c^{2}\right) =\left(d-6c\right)\left(d+6c\right) =\left(-6c+d\right)\left(6c+d\right) =2\left(-6c+d\right)\left(6c+d\right)$
