    • Are all real numbers a solution?

      This makes the solution would be all real numbers. When we say the solution is all real numbers, isolate the x term by subtracting x from both sides and you end up getting "2=2", which makes it a true statement, and therefore, the solution of the equation is all real numbers.

    • How real are real numbers?

      A real number is a rational or irrational number. Usually when people say "number" they usually mean "real number". The official symbol for real numbers is a bold R or a blackboard bold R {\displaystyle \mathbb {R} } . Some real numbers are called positive. A positive number is "bigger than zero".

    • How do you multiply decimals?

      How to Multiply Decimals Line up the numbers on top of each other. Multiply the numbers while ignoring the decimal points. Count up all of the numbers of digits that are located at the right side of the decimal points of the factors. Move the decimal point of the whole number to the left that number of times. Fill in the extra space with a zero. ... (more items) See More....

    • How do you find the discriminant?

      In a quadratic equation, the discriminant helps tell you the number of real solutions to a quadratic equation. The expression used to find the discriminant is the expression located under the radical in the quadratic formula! In this tutorial, get introduced to the discriminant of a quadratic equation!
