We have

$t_1 + t+2 = \dfrac{\sqrt{s}}{4} + \dfrac{s}{1100} = .5$

Multiplying through by 1100,

$275 \sqrt{s} + s = 550$

$275 \sqrt{s} = 550 - s$

Squaring (which means we need to check later),

$275^2 s = (550 - s)^2 = 550^2 - 1100 s + s^2$

$0 = s^2 - (1100 + 275^2) s + 550^2$

$0 = s^2 - 76725 s + 302500$

$s = \frac 1 2 (76725 \pm 1375 \sqrt{3113} )$

$s \approx 3.94285 \textrm{ or } s \approx 76721.0571$

Clearly there's no way that giant number would work; must be extraneous.

Answer: 3.94

What are the zeros of 2x^2+17x=-21

enyata [817]

$2x^2+17x+21=0\\D=17^2-4*2*21=121=11^2\\x_1=\frac{-17+11}{4} =-1,5\\x_2=\frac{-17-11}{4} =-7$

zeros of 2x^2+17x=-21 are (-7;0) and (-1,5)
