Question

Find the zeros of the polynomial 5x²+2x-3 and verify the relationship between the zeroes and the coefficients of the polynomial.​

Answer 1

Answer:

53+(−53)=53−53=0=50

Step-by-step explanation:

We first find the zeroes of the polynomial 5x2−3 by equating it to 0 as shown below:

5x2−3=0⇒5x2=3⇒x2=53⇒x=±53⇒x=53,x=−53 

 

Therefore, the zeroes of the given polynomial are 53 and −53.

Now, consider the sum of the zeroes as follows:

53+(−53)=53−53=0=50
