In the expression -7x-3x^2+5 what is the coefficient of x?
i don't understand what does coefficient is can you help?
Sure, I'd be happy to help explain!
In algebra, a coefficient is a constant that multiplies a variable. In this case, the variable is x. So, in the expression -7x - 3x^2 + 5, the coefficient of x is -7 for the term -7x.
To put it in a "fun" way, you can think of the coefficient as the part of the expression that gives x its "attitude." It's like the number that tells x how much to get dressed up. In this case, x has a coefficient of -7, so it's ready to rock its fancy attire!
Yes, I can help you understand what a coefficient is. In an algebraic expression, a coefficient is the number that multiplies a variable. In this expression, the variable is x.
In the term -7x, the coefficient is -7 because it multiplies the x. Similarly, in the term -3x^2, the coefficient is -3 because it multiplies x^2.
Therefore, in the given expression -7x - 3x^2 + 5, the coefficient of x is -7.
Of course! In an algebraic expression, a coefficient is the numerical factor that is multiplying a variable. In simple terms, it is the number in front of the variable.
In the given expression -7x - 3x^2 + 5, we can see two terms containing x: -7x and -3x^2. In both cases, the coefficient is the number that multiplies the x.
So, to find the coefficient of x, we just need to identify the numerical factor being multiplied with x in each term.
In the term -7x, the coefficient of x is -7. And in the term -3x^2, the coefficient of x^2 is -3.
Therefore, the coefficient of x in the expression -7x - 3x^2 + 5 is -7.
a polynomial has several terms, involving powers of a variable.
Each term is a constant times a variable raised to some power.
The terms are separated by + and -.
In each term the factors are multiplied.
In the given polynomial, the terms are
-7x, -3x^2, 5
The variable is x, the coefficient is the number multiplying the variable in its several powers. So, the coefficients are
-7, -3, 5
Surely your class text has explained this.
