If the common zero of 3x²-px+2 and 4x²- qx- 10 is 2 , than find the value of 2p -3q. About the author Caroline

Answer: 5 Step-by-step explanation: when x = 2 both the equations will be equated to zero. 3x²-px+2 => 3(2)²-p(2)+2 = 0 => 12 – 2p + 2 = 0 => 14 – 2p = 0 => 14 = 2p => p = 7 4x²-qx-10 => 4(2)²-q(2)-10 = 0 => 16-2q-10 = 0 => 6-2q = 0 => 6=2q => q = 3 2p – 3q => 2(7)-3(3) = 14-9 = 5 therefore ur answer 5. thank you pls mark as brainly Reply

Answer:5

Step-by-step explanation:when x = 2 both the equations will be equated to zero.

3x²-px+2

=> 3(2)²-p(2)+2 = 0

=> 12 – 2p + 2 = 0

=> 14 – 2p = 0

=> 14 = 2p

=> p = 7

4x²-qx-10

=> 4(2)²-q(2)-10 = 0

=> 16-2q-10 = 0

=> 6-2q = 0

=> 6=2q

=> q = 3

2p – 3q => 2(7)-3(3) = 14-9 = 5

therefore ur answer 5.
