Find the value of 56+9-(18÷6)×2 and show your work

56+9-3*2
56+9-6
59

56 + 9-(18/6) *2 (PEMDAS)
56+9-3*2
56+9-6
65-6
59

You use PEMDAS, and solve for what's inside the parenthesis first, and then you go by order of operations. You do multiplication next. Lastly, you go from left to right because all you have left is addition and subtraction. Your end result is 59

Hello!

the correct option is:

b. a value of the variable that makes the polynomial equal to zero.

why?

the root or roots of a polynomial are the values of the variable that makes the polynomial equal to 0. we can find the roots of a polynomial making the expression equal to 0 and then, isolating the variable (it it has just one variable).

for example, given the following polynomial:

the root or zero of the polynomial, can be found by making the expression equal to 0, and then, isolating the variable, so, finding the root we have:

therefore, we have that the root of the polynomial is equal to 2.

we must remember that the number of roots that a polynomial can have, will depend on the degree of the polynomial, a first degree polynomial have will have one single root, a second degree polynomial (quadratic expression) may have two roots and so.

hence the correct option is:

b. a value of the variable that makes the polynomial equal to zero.

have a nice day!
