Question

The sum of zero quadriaric polynimalx2-7x+5

Answer 1

Question:

What is the sum of zeros of the quadratic polynomial x² - 7x + 5.

Answer:

7

Solution:

We know that ,

If we have a quadratic polynomial

ax² + bx + c , then ;

Sum of zeros = -b/a

Product of zeros = c/a

Here,

The given quadratic polynomial is ;

x² - 7x + 5 .

Clearly,

a = 1

b = -7

c = 5

Thus,

The sum of the zeros of the given quadratic polynomial = -b/a

= -(-7)/1

= 7

Hence,

The sum of the zeros = 7

Moreover,

Product of zeros = c/a = 5/1 = 5
