Find all the zeros of the equation -2x^4+27x^2+1200=0

Angelina_Jolie [31]

For this case we have the following polynomial:
$-2x ^ 4 + 27x ^ 2 + 1200 = 0$
To solve the problem we apply the following steps:
1) We make a change of variables u = x ^ 2
2) We rewrite the polynomial
3) Solve the quadratic equation using the formula for the quadratic equation
4) We return the change and find four roots

Dmitry_Shevchenko [17]

Answer:

When x=2 the expression is undefined

Step-by-step explanation:

When the denominator is zero, the expression is undefined

2x-4 =0

2x=4

x=4/2

A differentiable function f has the property that f(5)=3 and fprime(5)=4. What is the estimate for f(4.8) using the local linear

icang [17]

The linear approximation means that you assume the function is linear. So, just do :
f(5) + f'(5) (x-5)

This works out, in this specific case
3 + 4 (- 0.2)

Hope this helps
