Question

The sum of the zeros of the quadratic polynomial is 7xsquare +24x+9

Answer 1

Answer:

-24/7

Step-by-step explanation:

Let p(x) = 7x² + 24x + 9

p(x) can be factorise as

= 7x² + 21x + 3x + 9

= 7x(x + 3) + 3(x + 3)

= (x + 3)(7x + 3)

=> x = - 3, - 3/7

Which are the zeros

So sum of zeros is ( - 3 + (-3/7))

= - 24/7
