Question

3x2 +11x + 30 splitting the middle term
​

Answer 1

Answer:

Formula used:-

x=-b±√b²-4ac/2a

Solution:-

• a=3
• b=11
• c=30

$\sf \implies \: x = \frac{ - 3± \sqrt{ {3}^{2} - 4(3)(30)} }{2(30)}$

$\sf \implies \:x = \frac{ - 3± \sqrt{9 + 360} }{60}$

$\sf \implies \: x = \frac{ - 3± \sqrt{369} }{60}$

$\sf \implies \: x = \frac{ - 3 + \sqrt{369} }{60} \: and \: x = \frac{ - 3 - \sqrt{369} }{60}$
