Question

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

Answer 1

Answer:

it is quadratic equation

Step-by-step explanation:

${(x + 1) }^{2} = 2(x - 8) \\ {x }^{2} + {1}^{2} + 2x = 2x - 16 \\ {x }^{2} + 1 = - 16 \\ {x }^{2} = - 17 \\ {x}^{2} - 17 = 0$

it is in the form of

$a {x}^{2} + bx - c$

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

so, it is quadratic equation
