Use the quadratic formula to solve x2 + 2x - 120 = 0. Think about what other method could also be used to solve this equation. a

pshichka [43]

Answer:

x = 10 , -12

Step-by-step explanation:

Solution:-

- The given quadratic equation is to be solved using the quadratic formula. The general form of a quadratic equation is:

$ax^2 + bx + c =0$

Where, [ a , b and c are constants ]

- The quadratic formula is given as:

$x = \frac{-b+/-\sqrt{b^2 - 4*a*c} }{2a}$

- The given equation is:

$x^2 + 2x - 120 = 0$

Where, a = 1 , b = 2 , c = -120

- Solve using quadratic formula:

$x = \frac{-2+/-\sqrt{2^2 - 4*1*(-120)} }{2*1}\\\\x = \frac{-2+/-\sqrt{4 + 480} }{2}\\\\x = \frac{-2+/-(22) }{2}\\\\\\x = 10 , -12$

PLEASE HELP ASAP IM REALLY TRING TO FINISH A stick has a length of $5$ units. The stick is then broken at two points, chosen at

Fed [463]

Answer:

0.16

Step-by-step explanation:

Length = 5 units
Number of broken sticks= 3
Equal lengths = 5 units/3

See the picture attached for reference.

As you see the best points are the green areas which covers 2 out of 5 zones.

Since it is same for both broken points, the probability of this is:

2/5*2/5 = 4/ 25 = 0.16

Answer is 0.16
