Answer 1

hope it helps u a lot

Answer 2

Answer :

Given that,

${(2x + 3)}^{2} - {(3x + 2)}^{2} = 13 \\ \\ \implies4 {x}^{2} + 12x + 9 - 9 {x}^{2} - 12x - 4 = 13 \\ \\ \implies - 5 {x}^{2} + 5 = 13 \\ \\ \implies5 {x}^{2} + 8 = 0$

The highest power of the variable "x" in the equation is 2. Thus the given equation is a quadratic one.
