Answer:
x²-x-6
Step-by-step explanation:
let alpha =2
beeta=-3
Then ,
alpha×beeta= 2×-3
=-6
alpha+beeta= -3+2
=-1
For quadratic equation
p(x) = x²+(alpha+beeta)x+(alpha.beeta)
=x²+(-1)x+(-6)
=x²-x-6

Given :-
Zeroes = 2 and -3
To Find :-
Equation
Solution :-
We know that
Sum of roots = α + β
Sum of roots = 2 + (-3)
Sum of roots = 2 - 3
Sum of roots = -1
Product of zeroes = αβ
Product of zeroes = (2)(-3)
Product of zeroes = -6
Now
Quadratic polynomial = x² - (α + β)x + αβ
Quadratic polynomial = x² - (-1)x + (-6)
Quadratic polynomial = x² + x - 6
