Question

Solve 5x 1 = 2x2 9x. which are steps in the process of completing the square used to solve the equation? 1 = 2(x2 2x) 1 = 2x2 4x 2 = 2(x2 2x 1) 3 = 2(x 1)2 2 = 2(x 1)2

Answer 1

Steps in the process of completing the square used to solve the given equation were discussed.

Given equation is:

$5x+1=2x^{2} +9x$, which is a quadratic equation

What is a quadratic equation?

Any equation of the form $ax^{2} +bx+c=0$ is called a quadratic equation where $a\neq 0$.

Taking all terms to the left side of the equation:

$-2x^{2} -9x+5x+1=0$

$-2x^{2} -4x+1=0$

$2x^{2} +4x=1$

$2(x^{2} +2x)=1$

To complete the square let us add 2 both sides

$2(x^{2} +2x)+2=3$

$2(x+1)^2=3$.....(1)

So, equation (1) is the required answer.

Hence, steps in the process of completing the square used to solve the given equation were discussed.
