Question

x(x+1)-8=(x+2)(x-2) is which eqution​

Answer 1

$\sf{Answer}$

Step by step explanation:-

x ( x +1) -8 = (x+2)(x-2)

x² + x -8 = x²-4

x² +x -8 -x² +4 =0

x² - x² +x -8 +4 =0

x -8 +4 =0

x -4 =0

Hence it is a linear equation

Used identity

(a +b) ( a-b) = a²-b²

Know more about Linear equation:-

The equation whose degree is 1 is called linear equation

It has only one zero

Its general form is ax +b =0 a is not equal to 0

Answer 2

Answer:

x ( x +1) -8 = (x+2)(x-2)

x² + x -8 = x²-4

x² +x -8 -x² +4 =0

x² - x² +x -8 +4 =0

x -8 +4 =0

x -4 =0

Hence it is a linear equation

Used identity

(a +b) ( a-b) = a²-b²
