Question

find the sum and product of zeroes without finding zeores of quadratic polynomial p(x)=3x²+7x+4​

Answer 1

Answer:

sum = -7/3 and product = 4/3

Step-by-step explanation:

for a quadratic polynomial (ax²+bx+c) , the methods to find sum and product of zeroes are -b/a and c/a respectively.

so in this equation

b = 7

c=4

a=3

so we just substitute them and we get the answer.

Answer 2

Given Quadratic expression 3x² - 4x + 7

compare this with ax² + bx + c , we get

a = 3 , b = -4 , c = 7

i ) Sum of the zeroes = - b/a

= - ( -4 )/3

= 4/3

ii ) Product of the zeroes = c/a

= 7/3
