Question

example of quadratic equation that can be solved by extracting the root with two real solution​

Answer 1

Answer:

A quadratic equation has two solutions. Either two distinct real solutions, one double real solution or two imaginary solutions. All methods start with setting the equation equal to zero.

Step-by-step explanation:

ax2+bx+c=0.

where a,b, and c are real numbers and a≠0. ...

ax2+c=0.

The equation 4x2−9=0 is in this form and can be solved by first isolating x2.

Here we see that x=±32 are solutions to the resulting equation. ...

Ifx2=k, then x=±√k.

(x+5)2=9.
