$\begin{gathered} 9(m-3)+3m=7m+43 \\ \text{Multiply the parenthesis by 9 and you have} \\ \\ (9\times m-9\times\lbrack-3\rbrack)+3m=7m+43 \\ \text{Next you have} \\ 9m-27+3m=7m+43 \\ \text{Note that the 9 multiplies the m to get 9m,} \\ \text{and the 9 also multiplies the negative 3 to arrive at negative 27.} \\ \text{After applying 9 to open the parenthesis, you now have } \\ 9m-27+3m=7m+43 \\ \text{You collect like terms.

X squared equals 922. The square root is a decimal which I can't use.

Step2247 [10]

If you need to siplify that radical, you should try to put all the numbers as product of prime factors.

922 = 2*461

2 and 461 are prime numbers. Then the transformation of the square root is √(922) = √(2*461) = (√2)(√461)

So you can use that in any expression to try to simpliy with other numbers whose prime factors include 2 and 461.
