Factor
=(2x - 3)(2x + 5)
roots (zero)
2x - 3 = 0
2x = 3
x = 3/2
x = 1.5
2x + 5 = 0
2x = -5
x = -5/2
x = -2.5
Its one, you get radical esquared which means ln e which is one if i remember correctly
Answer:
-3mn + 14n - m is your answer.
Step-by-step explanation:
Combine like terms (terms with the same amount of variables). Reorder so that it is so:
(-5mn + 2mn) + (6n + 8n) + (-4m + 3m)
Combine like terms. Add or subtract the variables. Note that if there is no number, it is assumed that there is a 1:
(-5mn + 2mn) = (2mn - 5mn) = -3mn
(6n + 8n) = 14n
(-4m + 3m) = 3m - 4m = -m
(-3mn) + (14n) + (-m)
-3mn + 14n - m is your answer.

Use y=-3x+5 on this equation 5x-4y=-3
5x-4(-3x+5) = -3
5x+12x-20 = -3
17x=17
x=1
y=-3x+5
for x=1;
y=-3+5
y=2
Answer: 4x+5 
4x-5
Step-by-step explanation: It's really hard to tell what the question is.
