Determine all three real numbers $a, \,b$ and $c$ which satisfies the conditions $a^2+ b^2+ c^2= 26$, $a + b = 5$ and $b + c\ge 7.$
Real numbers are numbers that can be found on the number line, including both positive and negative numbers, fractions, decimals, and irrational numbers like pi and square roots.
To find real numbers a, b, and c, you can use various mathematical equations and methods such as solving linear equations, graphing, or using algebraic expressions.
No, real numbers a, b, and c are not always unique. For example, in the equation x^2 = 4, both 2 and -2 are real numbers that can be used for a, b, and c.
Finding real numbers a, b, and c is often used in solving mathematical problems and equations, as well as in real-life applications such as in physics, engineering, and economics.
Yes, real numbers a, b, and c can be negative. As mentioned before, real numbers include both positive and negative numbers, as well as zero.
