Question

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

Answer 1

Step-by-step explanation:

• Applying the formula (a+b)^2 = a^2 + b^2 + 2ab
• x^2 + 1 + 2x = 2x - 6
• x^2 +2x -2x +1 -6
• x^2 -5
• Hence here a= 1 , b= 0 and c= -5
• So it is in form of quadratic equation....
• verified
