РАЗЛОЖИТЕ ** МНОЖИТЕЛИ

Question

РАЗЛОЖИТЕ НА МНОЖИТЕЛИ

---

Answer 1

9в²-4 = (3в-2) (3в+2)
4с²-1 = (2с-1) (2с+1)
25м²-36 = (5м-6) (5м+6)
49н²-81 = (7н-9) (7н+9)
64-16д² = (8-4д) (8+4д)
225-4х² = (15-2х) (15+2х)

Answer 2

9b²-4=(3b)²-2²=(3b-2)(3b+2)
4c²-1=(2c)²-1²=(2c-1)(2c+1)
25m²-36=(5m)²-6²=(5m-6)(5m+6)
49n²-81=(7n)²-9²=(7n-9)(7n+9)
64-16d²=8²-(4d)²=(8-4d)(8+4d)
225-4x²=15²-(2x)²=(15-2x)(15+2x)
