The quadratic equation is equivalent to this equation is C. x^2+2x-15=0
A quadratic equation is the second-order degree algebraic expression in a variable.
The standard form of this expression is ax² + bx + c = 0 where a. b are coefficients and x is the variable and c is a constant.
Given expression;
5/x=x+2/3
By cross multipication, we get
15 = x^2 + 2x
x^2+2x-15=0
Hence, the quadratic equation is equivalent to this equation is C. x^2+2x-15=0
