A triangle is drown inside the rectangle
and has an area x² + 5x+9. What area of
the rectangle is not included in the area
of the triangle ? Give the answer
with explantion.​

Answer 1

Step-by-step explanation:

Algebraic expression is formed from variables and constants using

different operations.

• Expressions are made up of terms.

• A term is the product of factors. Factors may be numerical as well as

algebraic (literal).

• Coefficient is the numerical factor in a term. Sometimes, any factor

in a term is called the coefficient of the remaining part of the term.

• The terms having the same algebraic factors are called like terms.

• The terms having different algebraic factors are called unlike terms.

• Expression with one term is called a 'Monomial’.

• Expression with two unlike terms is called a 'Binomial’.

• Expression with three unlike terms is called a 'Trinomial’.

• In general, an expression with one or more than one term (with non-

negative integral exponents of the variables) is called a ‘Polynomial’.

• The sum (or difference) of two like terms is a like term with coefficient

equal to the sum (or difference) of coefficients of the two like terms.
