Answer:
(3x + 5)(x - 6) = 0 (Assuming 3x is to the power of two 3x^2)
Step-by-step explanation:
Factor out -13 from -13x
3x^2 - 13(x) - 30 = 0
Rewrite -13 as 5 plus -18
3x^2 + (5 - 18)x - 30 = 0
Apply the distributive property
3x^2 + 5x - 18x - 30 = 0
Now factor out the GCF (Greatest common factor)
To do so we will group the first two terms and last two.
(3x^2 + 5x) - 18x - 30 = 0
Then factor out the GCF from each group.
x(3x + 5) - 6(3x + 5) = 0
(3x + 5)(x - 6) = 0
Answer:
-5/3 , 6
Step-by-step explanation:
Quadratic Formula is
x = -b ± √(b^2 − 4ac))/(2a)
replace the letters with the values from the equation, and plug it in.
x = -(-13) ± √((-13)^2 − 4*3(-30))/(2(3))
=
x = (13 ± 23) / 6
You may subtract or add the 13 and 23 for a valid answer, thus the two possible values are
-5/3
and
6
