Question

P(x) = 2x2 - kx + 7and Q(x) = 5x² + 2x - k
2
If P(2) = Q(3), the value of k =​

Answer 1

Answer:

-40 is the answer of the question..

Answer 2

Answer:

-36

Step-by-step explanation:

p(x)=2x^2-kx+7

p(2)=2(2^2)-2k+7

p(2)=2.4-2k+7

p(2)=8-2k+7

p(2)=15-2k

q(x)=5x^2+2x-k

q(3)=5(3^2)+2(3)-k

q(3)=45+6-k

q(3)=51-k

P(2)=Q(3)===>15-2k=51-k

::::-transport variables one side and constants one sides

-2k+k=51-15

-k=36

===>k=-36
