In a regular polygon each interior angle is 140 degree greater than each exterior angle . Calculate the number of sides of the ploygon

check above link.

graphically?   well, you graph them both, the solutions is where they both intersect each other, since there are two solutions, meaning they will meet twice, or namely the linear will run into the quadratic curve twice, and where they meet, those x,y coordinates are the solutions to the system.

(5x-1)^2= (5x)^2-2(5x)×1+(1)^2=25x^2-10x+1

differentiate (x^14(x^-2)^4with respect to the variable

the parentheses don't balance in your input.

differentiate 0 with respect to

the final answer is

0

hope this
