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

DanielleElmas [232]

To solve first move the 98 to the other side by subtracting it from both sides. Then divide by - 1 on both sides to that the x^2 is no longer a negative. You are left with:

$x^{2} = 98$

Now square root both sides to get

$x = +/- \sqrt{98}$

The two factors that make up 98 are 49 and 2. 49 can be square rooted. So we are left with these answers:

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

horrorfan [7]

p=3h + 3u subtract 3u from both sides

p-3u=3h now divide both sides by 3

h = p/3 - u
