If m=√17 -4 , then find the value of m^2+1/m^2 |
|
Answer» ong>ANSWER: i got that much only Step-by-step explanation: m^2 = 17 means that m = +/- sqrt(17) (m-1)*(m+1) becomes: (sqrt(17)-1)*(sqrt(17)+1 or: (-sqrt(17) - 1) * (-sqrt(17) + 1) if (sqrt(17)-1)*(sqrt(17)+1, then the PRODUCT of these 2 factors is PROCESSED as follows: sqrt(17) * sqrt(17) = 17 sqrt(17) * 1 = sqrt(17) -1 * sqrt(17) = -sqrt(17) |
