Which expression is equivalent to x^4 + 4x^2 - 45?

Step-by-step explanation:

The given expresion is

We can rewrite this as:

We obtained a quadratic equation in x²

Let us split the middle term to get:

We factor by grouping to get:

We factor further to get:

The correct answer is A.

answer: evaluate the objective function at each vertex to determine which - and -values, if any, maximize or minimize the function. example: find the minimum value and maximum value of the objective function f ( x , y ) = 4 x + 5 y , subject to the following constraints

step-by-step explanation:

use pothagarean therom

a^2+b^2=c^2 so first ac

acm is a right triangle because c= 90°

and am (the hypotenuse or c) =16+9 =25

but there is not enough info we need another angle or side length
