Question

The curve which represents a quadratic polynomial meets x axis at 2, 0 and -2, 0 .Form a quadratic polynomial(class10th)

Answer 1

Step-by-step explanation:

since the curve meets the x-axis at (2,0) and (-2,0)

let the curve be f(x)

therefore  

therefore x=2 and x =-2 are the zeroes of the polynomial f(x).

hence

hope this helps you.

cheers!!

Answer 2

Answer:

X2 - 4

Step-by-step explanation:

The curve meets x axis at (2,0) and (-2,0)

hence x=2 and x=-2

so the zeros of polynomial are 2 and -2

The polynomial with α and β is given by

x²-( α + β)x+ αβ

=x²-(2-2)x+2(-2)

=x²-4
