Question

Factor completely, then place the answer in the proper location on the grid. 6a^2 - 8a - 30

Answer 1

You can use the following sentence:


`x_1,_2 = (-b+- √(b^2-4ac) ) )/(2a)`

or if youre on a phone:
x_1,_2 = (-b+/-sqrt(b^2-4ac))/2a
where 6 is a, -8 is b, and 30 is c

in phone formatting:

x=(-(-8) +/- sqrt((-8)^2-4*6*-30))/2*6x=(8 +/- sqrt(64+720))/12
x=(8 +/- 28)/12

x_1= 36/12 = 3
x_2 = -20/12 = -5/3

Or on pc:

`x_1= (36)/(12) = 3 x_2 = -(20)/(12) = - (5)/(3)`

Answer 2

Answer is 2(3a + 5)(a - 3)

hope this helps! :)
