soal!!!

1.2x²+7x-15
2. 6x²-7x-24
3. 3x²+10x+3
4. 6x²+17x+5

Answer 1

1.2X²+7X- 15
=2X²+10X-3X- 15
=(2X²+10X)-3(X+5)
=2X(X+5)-3(X+5)
=(2X-3) (X+5)

2.6X²-7X-24
=6X²-X+12X-24
=(6X²-X)-4(X-6)
=?


3.3X²+10X+3
=3X²+9X+X+3
=(3X²+9X)+1(X+3)
=3X(X+3X)+1(X+3)
=(3X+1) (X+3)

4.6X²+17X+5
=?

Answer 2

4. 6x2+17x+5
6x2 + 15x +2x + 5
(3x+1)(2x+5)
