Solution of this polynomial equation is x = 3

<h2>What are polynomial equations ?</h2>

In mathematics, polynomial equation can be defined as the equation which consist of coefficient, variables and exponents. A polynomial equation has positive numbers as their exponent which is also known as its degree. All the equations such as quadratic equation, cubic equation which has non  negative number as their powers are part of polynomial equation.

Types of polynomial equations :

  • Monomial equation
  • Binomial equation
  • Cubic Equations
  • Linear Polynomial
  • Quadratic Polynomial

Some examples of polynomial equation are :

  • 2x+5
  • 3x = 9
  • 3x² + 5x+19
  • (x-3)³

According to question,

3x = 9

=> 3x / 3 = 9 /3

=> x = 3

Thus solution for given equation is x = 3.

One way to find a common denominator is by
Lena [83]

Answer:

Step-by-step explanation:

a). 1\frac{3}{5}=1+\frac{3}{5}

         =1+\frac{3}{5}\times \frac{4}{4}

         =1+\frac{12}{20}

         =1\frac{12}{20}

   1\frac{3}{4}=1+\frac{3}{4}

        =1+\frac{3}{4}\times \frac{5}{5}

        =1+\frac{15}{20}

        =1\frac{15}{20}

Therefore, common denominator of 20.

b). 2\frac{1}{2}=2+\frac{1}{2}

         =2+\frac{1}{2}\times \frac{5}{5}

         =2+\frac{5}{10}

         =2\frac{5}{10}

     \frac{4}{5}=\frac{4}{5}\times \frac{2}{2}

        =\frac{8}{10}

Common denominator of 10.

c). \frac{3}{8}=\frac{3}{8}\times \frac{6}{6}

       = \frac{18}{48}

   \frac{1}{6}=\frac{1}{6}\times \frac{8}{8}

      = \frac{8}{48}

Common denominator of 48.

The difference between two integers is 2. The larger integer is 11 less than twice the smaller. Find the smaller integer.
mr_godi [17]

Answer:

The smaller integer (y) is 3.

Step-by-step explanation:

x - y = 2   =  >  y = x - 2\\ x  = 2y - 11 \\ x = 2(x - 2) - 11 \\ x = 2x - 4 - 11 \\ x = 2x - 15 \\ 3x = 15 \\ x = 5 \\  \\ x - y = 2 \\ (5) - y = 2 \\  - y =  - 3 \\ y = 3

Therefore, the smaller integer, represented by y, is equal to 3.
