Write a quadratic function whose zeros are 7 and 2

Mathematics
1 answer:
sashaice [31]3 years ago
5 0

Answer:

A quadratic function whose zeros are 2 and 7 is f(x) = x^2 - 9x + 14

If the zeros of a quadratic function are a and b, the quadratic function will be given as:

f(x)  =  (x  -  a)(x  -  b)

For the function f(x) whose zeros are 2 and 7:

f(x)  =  (x  -  2)(x  -  7)

Expand the equation

f(x)= x^2 - 7x - 2x + 14

f(x) = x^2 - 9x + 14

Therefore, a quadratic function whose zeros are 2 and 7 is

f(x) = x^2 - 9x + 14

The correct option is (A) x^6 + x^5 - 2x^4  - 2x^3 + 3x^2 + 6x - 9 

Explanation:
The product of two polynomials:
(x^3 + x^2  -3)(x^3 - 2x + 3)

Row1:   x^6       x^5      -3x^3
Row2: -2x^4   -2x^3      6x
Row3:  3x^3     3x^2      -9

Add all of the above rows:
x^6 + x^5 - 3x^3 -2x^4 - 2x^3 + 6x + 3x^3 + 3x^2 -9

x^6 + x^5 - 2x^4  - 2x^3 + 3x^2 + 6x - 9 (Option A)
