Find the sum and product of zeros of 3x^2-5x+6
  • 1 answers

Gaurav Seth 5 years ago

we have to find sum and product of zeroes of the given polynomial 3x² - 5x + 6.

we know, for general form of quadratic polynomial, ax² + bx + c

  • sum of zeroes = - coefficient of x/coefficient of x² = -b/a
  • sum of zeroes = - coefficient of x/coefficient of x² = -b/a product of zeroes = constant/coefficient of x² = c/a

on comparing 3x² - 5x + 6 with ax² + bx + c we get, a = 3, b = -5 and c = 6

so, sum of zeroes = -b/a = -(-5)/3 = 5/3

product of zeroes = c/a = (6)/3 = 2

 

hence, sum of zeroes = 5/3

and product of zeroes = 2
