Question

If 2 is a zero of the polynomial p(x)= 4x^2+2x-5a then the find value of a

Answer 1

Heyaa☺☺
________________

Given,

p(x)=4x^2+2x-5a

=》p(2)=4(2)^2+2(2)-5a
=4(4)+4-5a
20-5a.(expression)

=》20-5a=0(equation)

Answer 2

Hi Mate!!!!


We know that sum of zeros of a given quadratic equations =. - 1 / 2

Let the other zero be = x

2 + x = - 1 / 2...... equation 1


2x = - 5a /4 ...... equation 2

from 1 and 2

a = 4


Have a great time!!!
