Answer:
Linear (❁´◡`❁)
Step-by-step explanation:
You can multiply or divide one equation so that it has a variable with a coefficient opposite of the other equation.
Example:
A) 2x + 3y = 6
B) 4x +2y = 20
Notice that neither equation has a "1" or "-1"
Let's multiply Equation A) by -2
A) -4x -6y = -12 Then add it to B)
B) 4x +2y = 20
-4y = 8
y= -2
A) 2x + 3*-2 = 6
2x = 12
x = 6
Answer: P = 0
Explanation:
2x^2 + Px - 2 = 0
2x^2/2 + Px/2 - 2/2 = 0/2
x^2 + Px/2 - 1 = 0
If we plug P = 0
x^2 + 0x/2 - 1 = 0
x^2 + 0 - 1 = 0
x^2 - 1 = 0
(x - 1)(x + 1) = 0
Answer:
IDK if correct but I also think the first
