radius of circle=2


so length of chord=2√2


let O be origin and P be mid-point of chord


OP=sqrt(4-2)=√2


so locus is x2+y2=2

prove that four straight lines represented by the equation 12x 2 +7xy -12y 2 =0 and 12x 2 +7xy -12y 2 -x +7y -10 form a square
 
 
Hello Student, 12x 2 +7xy -12y 2 =0 12x 2 +7xy -12y 2 -x +7y -10 with first x=(-7y +- yroot(49+144*4))/24 you will get 2 lines from here with second do the same thing x=(-7y+1 +-...

Find the greatest term in the expansion of (7-5x)^2 where x=2/3 Please explain the steps. Thankyou in advance.
 
 
Hello Student. Please find the solution (7-5x)^2 = 49 + 25x^2 – 70x so first term = 49 second term = -70*2/3 third term = 25 x^2 = 25*4/9 = 11.11 So 49 is greatest...
