Question

How many zeros does the function f(x) = 2x14 − 14x6 + 27x3 − 13x + 12 have?

Answer 1

Answer:

One.

Step-by-step explanation:

Now, as the function f(x) has only one part consisting x(the variable) it's normally for only one value of x, f(x) will turn out to be zero.

f(x) = 0 = 2x14 - 14x6 + 27x3 - 13x + 12

or, 0 = 28 - 84 + 81 + 12 - 13x

or, 13x = 37

or, x = 37/13

or, x = 2.85

So, for only one value of x, which is 2.85 f(x) will be zero.

Answer 2

Answer:

Step-by-step explanation:

14x6-45x3y3-14y6

let us foot x3= a and x3=b

so that

= 14x6-45x3y3-14y6

= 14a2- 45ab-14b2

=14a2-49ab+4ab-14b2

=(2a-7b) (7a+2b)

=14x6-45x3y3-14y2

= (2x3-7y3) (7x3+2y3)....
