###### Answer: -7xy3 + 8x2y2 – + 4×4 Linear Algebra

In mathematics a polynomial is an expression consisting of variables (also called indeterminates) and coefficients that involves only the operations of addition subtraction multiplication and non-negative integer exponentiation of variables. An example of a polynomial of a single indeterminate x is x 2 − 4x + 7.An example in three variables is x 3 + 2xyz 2 − yz + 1.

For example the polynomial + − which can also be written as + − has three terms. The first term has a degree of 5 (the sum of the powers 2 and 3 ) the second term has a degree of 1 and the last term has a degree of 0. Therefore the polynomial has a degree of 5 which is the highest degree of any term.

In mathematics and computing a root-finding algorithm is an algorithm for finding zeroes also called “roots” of continuous functions.A zero of a function f from the real numbers to real numbers or from the complex numbers to the complex numbers is a number x such that f(x) = 0.As generally the zeroes of a function cannot be computed exactly nor expressed in closed form root-finding …

Linear programming (LP also called linear optimization) is a method to achieve the best outcome (such as maximum profit or lowest cost) in a mathematical model whose requirements are represented by linear relationships.Linear programming is a special case of mathematical programming (also known as mathematical optimization).. More formally linear programming is a technique for the …

A fitted linear regression model can be used to identify the relationship between a single predictor variable x j and the response variable y when all the other predictor variables in the model are “held fixed”. Specifically the interpretation of β j is the expected change in y for a one-unit …
