A. 2x ^2 + 10x -3x -15 2x^2 + 7x - 15 b. 3x^2 +3xy -xy -y^2 3x^2 +2xy -y^2 c. 5m^2 + 20m - m - 4 5m^2 +19m - m
b. 3x^2+3xy-xy-y^2 = 3X^2+2XY-Y^2
c. 5M^2+20M-M-4 =5M^2+19M-4
d. 2p^2-8pq+pq-4q^2 = 2p^2-7pq-4q^2
e. 2a^2+3a-8a-12 =2a^2-5a-12
f. 2a^2-4ab+6ab-12b^2 =2a^2+2ab-12b^2
g. -15-3p-5p-p^2 = -15-8p-p^2
h. 35-5a+7a-a^2 = 35+2a-a^2
maaf ya klu jawaban q slh.....?
2x^2 + 7x - 15
b. 3x^2 +3xy -xy -y^2
