Option C
The solution of equation x^2+3x+4=0 is x= -3+- square root of -7/ 2
Solution: Need to identify correct option for solution of the equation x^2 + 3x + 4 = 0.
Given equation is quadratic equation. We can find solution of this equation using quadratic formula.
According to quadratic formula for general equation solution of the equation is given by
The given equation is So in our case, a = 1, b = 3 and c = 4
On applying quadratic formula we get
As i is square root of -1,
Hence correct option is C that is roots of quadratic equation
Step-by-step explanation: Tell me if i'm wrong
Answer:
71
Step-by-step explanation:
Divide 71 by 7 and you get 10 and 1 leftover. Divide 71 by 4 and you get 17 with 3 leftover.
If a were to be doubled, and be 10 more than the initial number, the value of a would also have to be 10 because when it is doubled, it becomes 20, and you can see that adding 10 to it will also make it be 20. The value of a would have to be 10.
Algebraic expressions are combinations of variables , numbers, and at least one arithmetic operation.
Your example: 5+6a+11b
Term: Each expression is made up of terms. A term can be a signed number, a variable, or a constant multiplied by a variable or variables.
Your example: 5, 6a, 11b
Factor: Something which is multiplied by something else. A factor can be a number, variable, term, or a longer expression.
Your example: 5, 6, a, 11, b
Coefficient: The numerical factor of a multiplication expression that contains a variable.
Your example: 6, 11
Constant: A number that cannot change its value.
Your example: 5
Answer: factors are 5, 6, a, 11, b
So from the coordinate, you know that x = 4 and y = -3.
So how about:
x = 4
y = -3
If you graph them the solution is (4, -3)
