What are the solution(s) of the quadratic equation 98 – x2 = 0? x = x = x = no real solution

Answered by wiki @ 09/11/2020

Answer:

Given the equation:

$98-x^2 = 0$

Subtract 98 from both sides we have;

$-x^2 = -98$

Multiply both sides by -1 we get;

$x^2 = 98$

Taking square root both sides we have;

$x = \pm \sqrt{98}= \pm \sqrt{49 \cdot 2}$

Simplify:

$x = \pm 7\sqrt{2}$

Therefore, the solutions of the quadratic equation are:

$x = 7\sqrt{2}$ and $x =-7\sqrt{2}$
