LHS = (2sinxcosx-cosx)/(1-sinx-cos^2x+sin^2x) = (2sinxcosx-cosx)/(sin^2x+cos^2x-sinx-cos^2x+sin^2x) = (2sinxcosx-cosx)/(2sin^2x+cos^2x) = cosx(2sinx-1)/sinx(2sinx-1) = cosx/sinx = cotx =RHS

m=-3/4 m=-4/3 easier to figure out the roots using the quadratic formula. {-b+\-[sqrt(b2-4ac)]}/2a (I hope you are aware of it). Before going and manually solving the eqn, its better to check if b2-4ac is positive or not.(if -ve, equation has imaginary
Yes it is equal.. The price has been increased by 70.6% and decreased by the same %.
2a^2+9a+4=0 2a^2+a+8a+4=0 a(2a+1)+4(2a+1)=0 (2a+1)(a+4)=0 a=-1/2 and a=-4
This is a second grade problem, actually.. Substitute for n 7*n 7*7565
X+2=5 X=5-2 X=3
48 2*24 then 2*2*12 then 2*2*2*6 then 2*2*2*2*3
lets start with the equation 2n(n+4) - 28 = (n+2)^2 using formula (a+b)^2=a^2+2ab+b^2 2n^2+8n-28=n^2+4n+32 simplyfying, n2+4n=32 Solving for n, we get n=4 So the even consecutive numbers are 4,6,and 8..... checking... 2(4*8)-28=36
