What are the zeros of the quadratic function F(x)=6x^2+12x-7

Mathematics

Daniel [21]3 years ago

Answer:

x = -1 + sqrt(78)/6

x = -1 - sqrt(78)/6

Step-by-step explanation:

Zeros are the x-values where the function is 0

f(x) = 0

6x² + 12x - 7 = 0

a = 6, b = 12, c = -7

Using Quadratic formula:

x = [-12 +- sqrt(12² - 4(6)(-7)]/2(6)

x = [-12 +- sqrt(312)]/12

x = [-12 + 2sqrt(78)]/12

x = -1 +- sqrt(78)/6

gary, Heather, and Irene want to find the zeros of the polynomial P(x). They evaluate the polynomial for different values and fi
LenKa [72]

Answer:

The answer is given below

Step-by-step explanation:

A number is said to be a zero of a polynomial if when the number is substituted into the function the result is zero. That is if a is a zero of polynomial f(x), therefore f(a) = 0.

Since  P(−1)=0 P(0)=1 P(2+√3)=0, therefore -1 and 2+√3 are zeros of the polynomial.

Gary is right because there are 2 known zeros of P(x) which are −1 and 2+√3. Also 2 - √3 is also a root. From irrational root theorem, irrational roots are in conjugate pairs i.e. if a+√b is a root, a-√b is also a root.

Heather is not correct because if P(0) = 1, it means that 0 is not a root. It does not mean that 1 is a zero of P(x)

Irene is correct. since P(−1) and P(2+3–√) equal 0, 2 zeros of P(x) are −1 and 2+√3. They may be other zeros of P(x), but there isn't enough information to determine any other zeros of P(x)
