Question

25.
Check whether the (x + 1)square = 2(x - 3) is quadratic equation or not?​

Answer 1

Answer:

$YES$

Step-by-step explanation:

$(x + 1) {}^{2} = 2(x - 3) \\ \\ x {}^{2} + 2x + 1 = 2x - 6 \\ x {}^{2} + 2x - 2x + 1 + 6 = 0 \\ x {}^{2} + 7 = 0$

here,

$a = 1, \: \: \: \: \: \\ b = 0, \\ c = 7$

here, it is of the form

$ax {}^{2} + bx + c = 0$

so, (x + 1)square = 2(x - 3) is quadratic equation
