× ( ײ - 3) = 4 is it quadratic equation or not​

Sagot :

✏️QUADRATIC

==============================

[tex] \large \bold{\blue{QUESTION:}} [/tex] Is it quadratic equation or not?

  • [tex] x (x² - 3) = 4 [/tex]

[tex] \large \bold{\blue{ANSWER:}} \: \: \Large \tt \red{NOT \: QUADRATIC} [/tex]

[tex] \large \bold{\blue{REASON:}} [/tex] Before we clarify if the equation is quadratic. Let us simplify the expression by distributing 'x' to the binomial.

  • [tex] x (x² - 3) = 4 [/tex]

  • [tex] x^3 - 3x = 4 [/tex]

» With the cube of 'x' or a variable 'x' is raised to 3, we can already say that the equation is Not Quadratic. A quadratic equation can only have a limit degree of two, which means there should be a variable that is squared or raised to the power of two but only limited to two.
