Check whether (x+1) ^2 = 2(x-8) is an quadratic equation or not

Answer:

it is quadratic equation

Step-by-step explanation:

[tex] {(x + 1) }^{2} = 2(x – 8) \\ {x }^{2} + {1}^{2} + 2x = 2x – 16 \\ {x }^{2} + 1 = – 16 \\ {x }^{2} = – 17 \\ {x}^{2} – 17 = 0 [/tex]

it is in the form of

[tex]a {x}^{2} + bx – c[/tex]

a=x. b=0. c=-17

so, it is quadratic equation
