Question

Solutions of pk garg class 10show that 2 and -2 are the zeros of the polynomial x square minus 4 and also verify the relationship between the zeros and the coefficient of the polynomial

Answer 1

Heyyyyy mate

here is your answer...


given polynomial= x^²-4

we can write it

(x^²-2^²)= (X+2) (x-2)


and zeroes are = x+2= 0

x= -2

x-2= 0

x= 2

verify

sum of zeroes= alpha+ beeta = 2+-2=0

product of zeroes= alpha× beeta = 2×-2= -4

coefficient of x^²/coefficient of X= -b/a= 0/2=0

constant term/ coefficient of x^²= -4/1= 4

hope it helps you
