Solving for w for the below eqn:
Addition ----- system%28w%5E2-2w%2B1%2C+2w-5%2Bw%5E2%29
cancel out --- system%28w%5E2-cross%282w%29%2B1%2Cw%5E2%2Bcross%282w%29-5%29
continuing ---> 2w%5E2-4=0
2w%5E2=4
cross%282%29w%5E2%2Fcross%282%29=cross%284%292%2Fcross%282%29
w=sqrt%282%29, ANSWER
want to check it out, go back both eqn:
%28sqrt%282%29%29%5E2-2sqrt%282%29%2B1%2B%282sqrt%282%29-5%2Bsqrt%282%29%5E2%29=0
2-2.8284%2B1%2B%282.8284-5%2B2%29=0
0.1716%2B%28-0.1716%29=0
0=0
Thank you,
