faktorkanlah bentuk aljabar berikut 6a^2+21ab+9b^2= 5a^2-23ab-10b^2= 8a^2-10ab-3b^2= 4a^2+17ab+4b^2= 8a^2+7ab-15b^2=

6a²+21ab+9b²=
(6a+3b)(a+3b)

5a²-23ab-10b²=
(5a +2b)(a -5b)

8a²-10ab-3b²=
(4a + b)(2a -3b)

4a²+17ab+4b²=
(4a + b)(a + 4b)

8a²+7ab-15b²=

6a^2 + 21ab + 9b^2 = (6a +3b) (a + 3b)
5a^2 - 23ab-10b^2 = (5a -2b) (a +5b:
8a^2 -10ab -3b^2 = (4a + b) (2a -3b)
4a^2 +17ab +4b^2 = (4a+b) (a+4b)
8a^2 +7ab -15b^2 = (8a +15b) (a - b )
