What are 4 examples of quadratic equation?Examples include:. 2x² - 64 = 0.. x² - 16 = 0.. 9x² + 49 = 0.. -2x² - 4 = 0.. 4x² + 81 = 0.. -x² - 9 = 0.. 3x² - 36 = 0.. 6x² + 144 = 0.. How do you answer the question completing the square?Correct answer:
Completing the square just means adding the same number to both sides of the equation -- which, remember, doesn't change the value of the equation -- in order to create a perfect square. In this case, we need to add 4 on both sides so that the right-hand side of the equation factors neatly.
What is quadratic equation examples with answers?So, basically, a quadratic equation is a polynomial whose highest degree is 2. Let us see some examples: 3x2+x+1, where a=3, b=1, c=1. 9x2-11x+5, where a=9, b=-11, c=5.
