I am still trying to solve for H in this equation but I am still lost
MgH = (1/2)*k*(H210)^2 + Mg*2
I was told to expand the square on the right, gather terms, put it in the standard quadratic form, and use the quadratic formula, but I don't know how.
Should it be Mgh=(H12)^2+25+1685?????

A=1/2h (b1 + b2) Solve for b1 A=1/2h (b1 + b2) Solve for b1 I assume this is A = (1/2)(h)(b1 + b2); i.e., the h is in the numerator and not the denominator Multiply both sides by 2. 2A = (2*1/2)h(b1 + b2). 2*1/2 on the right side is …
