Question

разложите на множители 144-m^4 n^4
(4m+6)^2-9
49d^2-25a^2
4-36a^6
4c^2-16m^2
64c^2-49d^2
25a^2-4n^2
(p+6)^2-196
(d+5)^2-81

Answer 1

(4m+6)^2-9=16m^2+48m+36-9=16m^2+48+27
49d^2-25a^2=(7b-5a)(7b+5a)
4-36a^6=(2-6a^2)(2+6a^2)
4c^2-16m^2=(2c-4m)(2c+4m)
64c^2-49d^2=(8c-7b)(8c+7b)
25a^2-4n^2=(5a-2n)(5a+2n)
(p+6)^2-196=p^2+12p+36-196=p^2+12p-160
(d+5)^2-81=d^2+10d+25-81=d^2+10d-56
