Question

Find the quadratic polynomial, for
U
the zeroes a. B given in each case
2.-1
po 19-1
divo 1.3
2​

Answer 1

Step-by-step explanation:

Sum of zeroes = 2+(-1) =2-1 =1

product of zeroes = 2×(-1)= -2

we know that any quadratic equation with real roots is in the form

u²+(sum of zeroes)u+(product of zeroes)

= u²+u+ (-2)

=u²+u -2

hence u²+u -2 is the required quadratic polynomial
