Korolek [52]

Answer:

2 {x}^{2}  - 6x - 1 = 0 \\ a = 2 \:  \:  \:  b =  - 6 \:  \:  \: c =  - 1 \\  \\ x =  \frac{6\binom{ + }{ - } \ \sqrt{  {6}^{2} - 4(2)( - 1)}   }{2 \times 2}  \\  \\ x =  \frac{6 \binom{ + }{ - } \sqrt{44}  }{4}  \\  x =  \frac{6 +  \sqrt{44} }{4} \\  \\  or x =  \frac{6 -  \sqrt{44} }{4}

I hope that is useful for you :)

PLEASE HELPP MEE ASAPP!!
WARRIOR [948]

Answer:

Step-by-step explanation:

each zero of the function will have a factor of (x - x₀)

h(x) = a(x + 3)(x + 2)(x - 1)

h(x) = a(x + 3)(x² + x - 2)

h(x) = a(x³ + 4x² + x - 6)

or the third option works if a = 1

however this equation gives us the points (0, -6) and (-1. -4), so "a" must be -2

h(x) = -2x³ - 8x² - 2x + 12

to fit ALL of the given points as it fits the three zeros and also h(0) and h(-1) so I guess that is why the given group is a <u><em>partial</em></u> set of solution sets
