Question

check the whether the following are quadratic equations (x+1) 2=2 (x-3)​

Answer 1

Aŋsweʀ :

we need to find out whether the Given equation is a quadratic equation or not.

Let's check out :

$\sf \dashrightarrow \:(x + 1)2 = 2(x - 3) \\ \\ \sf \dashrightarrow \:2x + 2 = 2x - 6 \\ \\ \sf \dashrightarrow \:2x - 2x = - 6 - 2 \\ \\ \sf \dashrightarrow \: 0 = - 8$

Hence,

• the given equation is not a quadratic equation

Answer 2

2(x+1)=2(x-3)

2x+2=2x-3

2x-2x=-2-3

-5=0

${0x}^{2} + {0y}^{2} - 5 = 0$

HENCE IT IS A QUADRATIC EQUATION..
