Step 1: You can distribute it by multiplying 6 by 2x and -12, so you get 12x-72= 24
Step 2: Now you can solve it by adding 72 on both sides, so we get 12x= 96, then you can divide 12 on both sides, so we get x=8.
Answer:
Below in BOLD.
Step-by-step explanation:
1. The discriminant D = b^2 - 4ac
= 3^2 - 4*5*(-7)
= 9 + 140
= 149.
Positive value so it has 2 real solutions.
2. D = (-12)^2 - 4 * 9 * 4
= 144 - 144
= 0.
So it has one real solution.
3. D = 2^2 - 4*1*3
= -8.
It is negative so there are No real solutions.
4. D = 4^2 - 4*2*10 = 16 - 80 = -64.
No solutions.
5. D = (-12)^2 - 4*3*(12)
= 144 - 144 = 0
So its the second choice.
I dont think so but to justify quads means four and the is no sign of x to the fourth power or y to the fourth power ect.
Answer:
2
Step-by-step explanation:
The degree of a function is the highest power any single term is raised to.
x^2 is the term that has the highest degree, so in this case, the degree is 2.
For example; in x^5-x^4-3x^3; the degree would be 5 because the highest power x is raised to is 5.
The square root of -1 is i. So you can simplify it to 7(sqrt)-1, which becomes 7i.
