Question

y*+8y+8=60 usando formula de baskara

Answer 1

y²+8y+8=60

y²+8y+8-60=0

y²+8y-52=0

y= $\frac{ -b+-\sqrt{delta} }{2a}$

Delta (Δ) = b²-4ac = 8²-4(-52) = 64 +208 = 272

y= $\frac{-8+-\sqrt{272} }{2}$

y= $\frac{-8+-4\sqrt{17} }{2}$

y= -4 +- $2\sqrt{17}$

y'= -4 + $2\sqrt{17}$

y"= -4 - $2\sqrt{17}$
