Hi
Just told you : first know by heart remarkable identities !
Then apply :
4x²-12x = -9
4x²-12x +9 =0
(2x-3)² = 0
(2x-3) (2x-3) = 0
Now you have a double solution :
2x-3 = 0
and 2x -3 = 0
I let you try !
Answer:
= 
To find equivalent fractions, multiply be any number that is the same for the numerator/denominator
You can also divide, but it must be divisible by both the numerator/denominator
Answer:
the lines intersect at (4,-2)
3y + 5.2 = 2 - 5y
3y + 5y + 5.2 = 2
8y = 2 - 5.2
8y = -3.2
y = (-3.2) / 8
y = -0.4
Answer:
A line has one dimension because it is made up of all points that extend infinitely in either direction.
