Question

Solve using the quadratic formula. h2 + 8h + 8 = 0 Write your answers as integers, proper or improper fractions in simplest form, or decimals rounded to the nearest hundredth. h = or h =

Answer 1

A=1 b=8 c=8
h = [-8 +-sq root(64 - 4*1*8)] / 2
h = [-8 +-sq root(32)] / 2
h1 = -4 + 2.8284271247
h1 = -1.1715728753
h2 = -4 - 2.8284271247
h2 = - 6.8284271247
