(2x-p)(3x+2)=6x²+5x+q求P,q

(2x-p)(3x+2)=6x²+5x+q求P,q
(2x-p)(3x+2)=6x²+5x+q求P,q

(2x-p)(3x+2)=6x²+5x+q求P,q
(2x-p)(3x+2)=6x^2+(4-3p)x-2p=6x^2+5x+q..4-3p=5,q=-2p,所以 p=-1/3,q=2/3

(2x-p)(3x+2)=6x²+5x+q
6x²＋（4-3p）x-2p=6x²+5x+q
所以
4-3p=5
-2p=q
即
p=-1/3
q=2/3

(2x-p)(3x+2)=6x²+5x+q
6x^2+(4-3p)x-2p=6x²+5x+q
4-3p=5
p=-1/3
q==-2p=-2*(-1/3)=2/3

解；原式=6x²-（4+3px）-2p=6x²+5x+q
-（4+3px）=5x 得出p=-3
-2p=q 得出q=6
