Rearrange this expression into quadratic form ax2 bx c 0 02

Rearrange this expression into quadratic form, ax2 bx c = 0 0.20=(x^2/65-x) where a=1, and identify the values of b & c

Solution

Rearrange this expression into quadratic form, ax^2 +bx +c

0.20 = x^2/(65 -x)

Multiply both sides by (65 -x)

0.20(65 -x) = x^2

x^2 + 0.20x - 13 =0

Cpomparing with standard equation : a= 1 ; b = 0.20 ; c= -13
