Question

if a and b are zeroes of the polynomial x2-x-6, then find the quadratic polynomial of (2a+3b) abd (3a+2b) ​

Answer 1

Answer:

0 and 5.

Step-by-step explanation:

x^2-x-6

=> x^2-3x+2x-6=0

=> x(x-3)+2(x-3)=0

=> (x-3)(x+2)=0

=> x=3 or x=-2

Let us consider a=3 and b=-2

Now, (2a+3b) = 6+(-6) = 0.

Also, (3a+2b) = 9+2(-2) = 5.
