Question

What are the solutions of the equation x squared equals 4? Use a graph of the related function.

Answer 1

In the graph of quadratic equation, the parabola passes through the points left parenthesis (-2,0) right parenthesis, left parenthesis (0,-4) right parenthesis, and left parenthesis (2,0) right parenthesis.

What is a quadratic equation?

A quadratic equation is the equation in which the unknown variable is one and the highest power of the unknown variable is two.

The standard form of the quadratic equation is,

$ax^2+bx+c=0$

Here,(a,b, c) is the real numbers and (x) is the variable.

The given quadratic equation is,

$f(x)=x^2+4$

Equate the equation to zero to solve it further,

$x^2=4\\x^2-4=0\\x^2=4\\x=\sqrt{4}\\x=\pm2$

Thus, the solution of the equation is +2 and -2. The graph of the equation is attached below.

Hence, in the graph of quadratic equation, the parabola passes through the points left parenthesis (-2,0) right parenthesis, left parenthesis (0,-4) right parenthesis, and left parenthesis (2,0) right parenthesis.
