Question

What are the solution(s) of the quadratic equation 98 – x2 = 0?

x = Plus or minus 2 StartRoot 7 EndRoot
x = Plus or minus 6 StartRoot 3 EndRoot
x = Plus or minus 7 StartRoot 2 EndRoot
no real solution

Answer 1

This is easier, you can give it a try.

Answer 2

x = Plus or minus 7 StartRoot 2 EndRoot

Answer 3

C is the answer

Answer 4

Update of the answer choices to be viewed easier:

\(A\) - \(x = \underline{+} 2\sqrt{7}\)
\(B\) - \(x = \underline{+} 6\sqrt{3}\)
\(C\) - \(x = \underline{+} 7\sqrt{2}\)
\(D\) - \(no~real~solution\)

Answer 5

I am sorry, I understand. Anyhow you should try to learn. You need to get an idea about the equation for solving quadratic equations.

Answer 6

so 3. 3 is C
That's what i said first

Answer 7

thank you guys

Answer 8

Here, I'll explain it.

Answer 9

this is how it looks
x = ±7√2

Answer 10

\(98 – x^2 = 0\) get x by itself

\(– x^2 = -98\) divide both sides by 1

\(x^2 = 98\) square 98

\(x = \underline{+}\sqrt{98}\) figure out 98

\(x = \underline{+}7\sqrt{2}\) answer
