Question

check whether the given equation, (x+2)^2=4(x+3) is quadratic equation or not​

Answer 1

Answer:

(x+2)^2=4(x+3)

x^2+4+4x=4x+12

x^2+4x-4x+4-12=0

x^2-8=0

The degree of polynomial is 2

So, It is a quadratic equation

Answer 2

Given,

An equation (x+2)² = 4(x+3).

To Find,

Whether the given equation is quadratic or not.

Solution,

The given equation is (x+2)² = 4(x+3)

Solving this equation by using the formula (a+b)² = a²+b²+2ab

x²+4+4x = 4x+3

x²+4x-4x+4-3 = 0

x²+4-3 = 0

x²+1 = 0

The degree of the equation comes out to be 2.

Hence, (x+2)² = 4(X+3) ia a quadratic equation.
