a) Factor to (x+2)(x-8) = 0, x = -2 or 8
b) First divide both sides by 3 to make the coefficients simpler --> 2x^2 + x - 6 = 0. Then we use the quadratic formula:
}}{4} = \frac{-1 \pm 7}{4} = \frac{3}{2}, -2)
, roots are 3/2 and -2.
You do not need to type "Read the information...root" because we do not have your assignment list, and most of us already know how to input math expressions using LaTeX or the code that algebra.com has.
c) Incomplete.
