Question

find a quadratic polynomial whose one zero is 7 and sum of zeros is 0.

Answer 1

sum is 0

other zero is -7

product = -49

required polynomial is
${x}^{2} - 49$

Answer 2

heya

here is ur answer

===========================

given :-

one of the zero of polynomial =7

sum of zeros = 0

let another zero of the polynomial be X

so

X +7 = 0

X = (-7)

let's find product of the Zeros

✒ 7×(-7) (-49)


v all know that.sum of zeros is equal to -b/a

✒0 = - b /a

✒ -49 = c/a

so from this v can say write the quadratic polynomial.

a= 1

b = -0

c= -49

✴ general form of a quadratic polynomial is.

${ax}^{2} + bx + c = 0$

so the required quadratic polynomial is

${x}^{2} - 49$
