\text{ if } \Delta=0\text{ then there is one x-intercept : }x=-\dfrac{b}{2a}\\\\
\text{ if } \Delta\ \textless \ 0\text{ then there are no x-intercept : } x=\varnothing\\\\
\text{ if } \Delta>0\text{ then there are two x-intercept : }x_1,x_2=\dfrac{-b\pm\sqrt{\Delta}}{2a}\\\\

I need help answering this question, Asap

Answer:

(-65)/17

Step-by-step explanation:

Evaluate 3/(x - 2) - sqrt(x - 3) where x = 19:

3/(x - 2) - sqrt(x - 3) = 3/(19 - 2) - sqrt(19 - 3)

19 - 3 = 16:

3/(19 - 2) - sqrt(16)

19 - 2 = 17:

3/17 - sqrt(16)

sqrt(16) = sqrt(2^4) = 2^2:

3/17 - 2^2

2^2 = 4:

3/17 - 4

Put 3/17 - 4 over the common denominator 17. 3/17 - 4 = 3/17 + (17 (-4))/17:

3/17 - (4×17)/17

17 (-4) = -68:

3/17 + (-68)/17

3/17 - 68/17 = (3 - 68)/17:

(3 - 68)/17

3 - 68 = -65:

Answer: (-65)/17
