Can anybody explain how I can get the equation.​

Mathematics
1 answer:
antoniya [11.8K]3 years ago
5 0

Step-by-step explanation:

If the polynomial is rational, then one of zeros is 3 + 2i.

We are also given f(x) is decreasing function, it means the leading coefficient is negative.

<u>The factors would be:</u>

  • f(x) = - (x - 7)(x - (3 - 2i))(x - (3 + 2i)

or

  • f(x) = - (x - 7)(x - 3+ 2i)(x - 3 - 2i)

Solve the quadratic equation by using a graphic approach. Round your answer to the hundredths place,
NeX [460]

Answer:

Step-by-step explanation:

Well, I really don’t like graphic approaches in math, so hear ya go a formula:

Although there are easier ways that work for some quadratics, but this formula works for them all. (It is atached, have a look)

So,

( -(-2)+- square root of ((-2)^2-4(1)(-40)) ) / 2(1)

Note that for a hear I use one, since there is nothing in front of x.

( 2 + (12.8) ) / 2 < with plus

( 2 -(12.8) ) / 2 < with minus

X = 7.4

Or

X = -5.4

(Quad equations have 2 answers)
