Question

solve if a and B are the zeroes of the polynomial 2x square+7x+5 write the value of a+B+aB

Answer 1

As a and B are two zeroes of equation

2x^2+7x+5 so

a+B=-b/a

a+B=-7/2

&

aB=c/a

aB=5/2

Now,

a+B+aB=-7/2+5/2

=-2/2

=-1

Answer 2

As a and B are two zeroes of equation

2x^2+7x+5 so

a+B=-b/a

a+B = -7/2

&

aB=c/a

aB=5/2

Now, a+ B+aB = -7/2+5/2

= -2/2

=-1
