Answer:
Difference between algebraic expression and polynomial
Step-by-step explanation:
Algebraic expression:
- An algebraic expression is made up of variable, constants and arithmetic operators like addition, subtraction, etc.
Polynomial
- A polynomial is an expression consisting of variables and coefficients, that involves operations like addition, subtraction, multiplication.
- A polynomial cannot have negative exponential powers.
Difference between algebraic expression and polynomial
- All polynomials are algebraic expression.
- All algebraic expression cannot be polynomials.
- Polynomial must have no negative exponents.
- Polynomial does not have variable inside radical system.
The given equation is:
Cross multiplication would have given us
..................(Equation 1)
Now, if we use the multiplication property of equality to multiply both sides of the equation by 10, we will get:
This will become , which is the same as (Equation 1) which we had got from cross multiplication.
Thus, out of the given options, the <u>third option</u>, "using the multiplication property of equality to multiply both sides of the equation by 10" is the correct one.
To get the two equation we simply factorize first.
2x^2-2x-12=0
dividing through by 2 we get
x^2-x-6=0
factorizing the above we get:
x^2+2x-3x-6=0
x(x+2)-3(x+2)=0
(x+2)(x-3)=0
hence the equation will be:
x+2=0
x-3=0
Answer:
Step-by-step explanation:
Divide each term by and simplify.
