Question 17 and 18..............

Answer 1

Answer:

5x²-4x+3

Explanation:

Sum of zeores = -b/a

Product of zeores= c/a

Sum of zeores = -(-4/5)

Product of zeores = 3/5

Sum of zeores= 4/5 ANS

Product of zeores = 3/5

Answer 2

Answer: There are two ways first is by finding factors and then zeros and then sum and second is by short cut I am doing below;

Q. 17

Solution . Sum of zeros = -b/a

so ,Sum of zeros = -[-4]/5=4/5

And product of zeros = c/a

So Product of zeros = 3/5
