Question

find the zeroes of the quadratic polynomial and verify the relationship between the zeroes and their coefficients ​

Answer 1

Answer:

a. 25x(x+1)+4

=25x²+25x+4

THEREFORE it is Quadratic polynomial

" coefficient of x²=25

b. 63-2x-x²

=x²+2x-63

the coefficient of x² is 1

we can solve it by using middle term breaking

c . 49x²-81

it is Quadratic polynomial

therefore co- efficient of x² is 49

now,solving

49x²-81

49x²-81=0

49x²=81

x²=81/49

x=root over 81/49

x=9/7

therefore x=+- 9/7
