what are the solution(s) of the quadratic equation 98 - x² = 0?\no x = ±2√7\no x = ±6√3\no x = ±7√2\no no real solution
Answer
Answer:
C. $x = \pm7\sqrt{2}$
Explanation:
Step1: Isolate $x^{2}$
$98 - x^{2}=0$ can be rewritten as $x^{2}=98$.
Step2: Take square - root of both sides
$x=\pm\sqrt{98}$.
Step3: Simplify $\sqrt{98}$
$\sqrt{98}=\sqrt{49\times2}=\sqrt{49}\times\sqrt{2}=7\sqrt{2}$. So $x = \pm7\sqrt{2}$.
