Answer:did u ever find the answer i need it

Step-by-step explanation:

**Answer:**

look up something called desmos and type in the equation

**Step-by-step explanation:**

So first set one side to zero

subtract 5 from both sides

3r^2-16r-12=0

factor

to find the factor in

ax^2+bx+c form when a>1

multiply a and c together

find what 2 numbers add up to b and multiply to ac so

a=3

b=-16

c=-12

ac=3 times -12=-36

factors that add up to -16

2 and -18 is the answer since 2 times -18=-36 and 2-18=-16 so

split the middle number up

3r^2-16r-12=0

3r^2-18r+2r-12=0

group

(3r^2-18r)+(2r-12)=0

factor out common factors

(3r)(r-6)+(2)(r-6)=0

reverse distribute (ab+ac=a(b+c) so

(3r+2)(r-6)=0

set each to zero

r-6=0

add 6

r=6

3r+2=0

subtract 2

3r=-2

divide 3

r=-2/3

r=6 or -2/3

Pls where is the question actually??
