What is the quadratic formula of #0=10x^2 + 9x-1#?
natali 33 [55]
Quadratic formula is:

x =  \frac{- b +/-  \sqrt{ b^{2} - 4ac} }{2a}

Plug in:

x =  \frac{-9 +/-  \sqrt{9^{2} - 4(10)(-1)} }{2(10)}

x =  \frac{-9 +/-  \sqrt{81 + 40}}{20}

x =  \frac{- 9 +/-  \sqrt{121}}{20}

x =  \frac{- 9 +/- 11}{20}

x =  \frac{-9 - 11}{20} and x =  \frac{- 9 + 11}{20}

x =  \frac{- 20}{20} and x =  \frac{2}{20}

x = - 1,  \frac{1}{10}

Answer:  4h - 3

<u>Step-by-step explanation:</u>

f(h - 1) = 3(h - 1) + h

          = 3h - 3 + h

          = 4h - 3
