Question

Is (x+2)²=5 a quadratic equation ​

Answer 1

Step-by-step explanation:

(x+2)^2 = 5

x^2 + 4x + 4 = 5

x^2 + 4x + 4 - 5 = 0

x^2 + 4x - 1 = 0

hence, this is in the form ax^2 + bx + c = 0.

•°• (x+2)^2 = 5 is a quadratic equation.

Answer 2

(x+2)^2=5

x^2+4x+2^2=5 [by using (a+b)^2=a^2+2ab+b^2]

x^2+4x+4-5=0

x^2+4x-1=0

yes it is a quadratic equation
