Simplifying equations with square roots
Webbisolate the square root on one side of the equation square both sides of the equation Then continue with our solution! Example: solve √ (2x+9) − 5 = 0 isolate the square root: √ (2x+9) = 5 square both sides: 2x+9 = 25 Now it should be easier to solve! Move 9 to right: 2x = 25 − 9 = 16 Divide by 2: x = 16/2 = 8 Answer: x = 8 WebbThe option "Only simplify, no answers as decimals" forces the answer NOT to be given as a rounded decimal, but instead the answer is simplified if possible, and the square root is left in the answer if it cannot be simplified. For example, an answer of √ 28 will be given in simplified form as 2√ 7. This option is useful for algebra 1 and 2 courses.
