Question

One of the sum of zero of quadratic polynomial x²-4x+c is -3. Find the value of c.

Answer 1

Answer:

Given Sum of zeros in polynomial x2+4x+8 is

If we take a polynomial and then a factor out of it we may get

f(x) = p(x - a)(x - b)(x - c) and so on

here the roots are a, b, c where the polynomial is zero.

Now consider a quadratic equation ax^2 + bx + c

By adding the roots will be - b/a

here b = 4 and a = 1

 = - b / a = - 4 /1

So sum of roots of polynomial is - 4
