Answer:
To divide, use / instead of \.
Examples: 1+2, 1/3+1/4, 2^3 * 2^2
(x+1)(x+2) (Simplify Example), 2x^2+2y x=5, y=3 (Evaluate Example)
y=x^2+1 (Graph Example), 4x+2=2(x+6) (Solve Example)
Step-by-step explanation:
example
When a quadratic equation ax^2+bx+c has a double root, the discriminant,
D=b^2-4ac=0
Here
a=2,
b=b,
c=18
and
D=b^2-4ac=b^2-4*2*18=0
solve for b
b^2-144=0
=> b= ± sqrt(144)= ± 12
So in order that the given equation has double roots, the possible values of b are ± 12.
Step-by-step explanation:
sorry I don't now but when I now I will tell you ok but mybe it 12×12×12
Answer:
2. quadrant 4
3. quadrant 2
4. quadrant 3
Step-by-step explanation:
You can refer to the picture.
2. Since 
less than 0 which means is negative, 
less than 0 which means is negative.
So, the angle lies in quadrant 4 (Cos quadrant)
3. Since less than 0 which means is negative, 
less than 0 which means is negative.
So, the angle lies in quadrant 2 (Sin quadrant)
4. Since more than 0 which means is positive, less than 0 which means is negative.
So, the angle lies in quadrant 3 (tan quadrant)
