Answer:

x is 4.30 and 0.697

Step-by-step explanation:

Quadratic formular:

$x = \frac{ - b± \sqrt{ {b}^{2} - 4ac } }{2a} \\$

a » 1

b » -5

c » 3

$x = \frac{ - ( - 5)± \sqrt{ {( - 5)}^{2} - (4 \times 1 \times 3)} }{(2 \times 1)} \\ \\ x = \frac{5± \sqrt{13} }{2}$

Therefore, values of x :

$x = \frac{5 + \sqrt{13} }{2} \: \: and \: \: \frac{5 - \sqrt{13} }{2} \\ \\ x = 4.30 \: \: and \: \: 0.697$

Try this explanation:

Note, in the 1st row given '9x', in the 2d one - '9(0)', then it means the substitution '0' instead of 'x'. In other words <u>x=0</u> !

answer: x-intercept is '0', y-intercept is '12'
