Question

If the zero of the quadratic polynomial x2+x-2 is -2 find the other zero

Answer 1

Heya !!!


Let Alpha = -2




P(X) = X²+X -2


Here,



A = Coefficient of X² = 1


B = Coefficient of X = 1


And,

C = Constant term = -2


Sum of zeroes = -B/A



-2 + Beta = -1/1




Beta = -1+2 = 1

Answer 2

Let Alpha = -2

P(X) = X2+X -2

Here,

A= Coefficient of X2 = 1

B = Coefficient of X = 1

And,

C = Constant term = -2

Sum of zeroes = -B/A

-2 + beta = -1/1

beta =-1+2=1
