two rectangles have same area 480 sft .thier lengths differ by 6ft and thier breadths by 4ft.find the dimensions.
A pipe takes 3hours less than another to fill a water tank. if the two together can fill the tank in 3hours 36minutes, find the time taken by each independently to fill the tank.
if m and n r the roots of the eqn. x2+x-2=0, frame the eqn whose roots are m/n and n/m
solve:3x-8/x-2=5x-2/x+9
how to diferentiate between a pure quadratic equation and adfected qudratic equation?

x+y=40
x-y=4
1) x^2+x-(a-2)(a+1)=0
2x-3=(?2x? -2x+21)
Q.
1)p^ square -12k+9=p
2)(p+1)n^square +2(p+3)n+(p+8)=p
3)(3p+1)c^square+2(p+1)c+p=0
(a) equal (b) distinct (c) imaginary
1)a square - ma +1=0
2) x square -mx+9=0
3) r square -(m+1) r+4=0
Why we should take the number (10x+y) ?
