A=-2;b=9;c=9;
delta=b^2-4*a*c
root1=(-b+(delta^(0.5)))/(2*a)
<span>root2=(-b-(delta^(0.5)))/(2*a)
delta =153
root1 = -0.8423
root2 =<span> 5.3423
Correct Answer is D</span></span>
You'll need to use parentheses to indicate what is under the first radical sign and what is not. Did you mean radical(36a) or just radical 36?
I will assume that you meant radical(36a).
Then you have [radical(36a}*(b^4)*c^5.
This comes out to 6sqrt(a)*b^4*c^5.
5x- SR 40= 0., add to the other side, 5x= SR 40. divide both sides by 5, x= SR of 8, or 2 SR 2
