Question

The polynomial equation x (x + 1) + 8 = (x + 2) (x – 2) is ​

Answer 1

Answer:

linear equation in one variable

Step-by-step explanation:

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

x² + x + 8 = x² - 2² [a²-b² = (a+b)(a-b)]

x² + x + 8 = x² - 4

x² - x² + x + 8 + 4 = 0

x + 12 = 0

this polynomial equation is linear equation in one variable.
