Write in Standard Form (x)(x)=4

$(x) (x) = 4$

Subtract $4$ from both sides of the equation.

$(x) (x) - 4 = 0$

Multiply $x$ by $x$ .

$x^{2} - 4 = 0$

To write a polynomial in standard form, simplify and then arrange the terms in descending order.

$a x^{2} + b x + c = 0$

The standard form is $x^{2} - 4$ .

$x^{2} - 4 = 0$
