Question

find the zero of polynomial 4xsquare -25​

Answer 1

⏭️ Ur Answer Is At Last:

⏭️ Step-by-step explanation:

To find zeroes we have to put this equation equals to 0...

4x^2-25 = 0

(2x)^2-(5)^2 = 0

By using the formulae a^2-b^2=(a+b)(a-b)

Then equation will be

(2x+5)(2x-5)=0

Our first zero will be

2x+5=0 => 2x= -5 => x= -5/2

Also

Our second zero will be

2x-5=0 => 2x=5 => x=5/2

So our required zeroes are 5/2 and -5/2...
