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)
