Question

If 2 and -3 are the zeroes of the quadratic polynomial x²+(a+1)x+b, then find the values of a and b.If 2 and -3 are the zeroes of the quadratic polynomial x²+(a+1)x+b, then find the values of a and b.​

Answer 1

Solution :

Given, 2P−3<8

Adding 3 to both sides, we get

→2P − 3 + 3 < 8 + 3

→2P < 11

Dividing both sides by 2, we get

→ P < 11/2

→ P<5.5

∴A = {0,1,2,3,4,5}

The number of elements in the set A is 6.

∴ Cardinal number of set A = 6
