Answer:
k= −2x−16
/x
Step-by-step explanation:
(Observed data - Accepted standard) divided by the accepted standard. Then all of that is multiplied by 100.
( ( O - A ) / A) * 100
<span>2x^2+8x-7=-2
</span><span>2x^2+8x - 5 = 0
using the formula:- x = [-8 +/- sqrt(8^2 - 4*2*-5) ] / 4
= -2 +/- sqrt 104)/2
= 0.5495 , -4.549
