7x − one over two (8x + 4) = 6 step 1: 7x − 4x − 2 = 6 step 2: 3x − 2 = 6 step 3: 3x − 2 + 2 = 6 step 4: 3x = 6 step 5: x = 2 which step was the error made and why?

Step 3 was made error because 2 is not added to the right side of the equation.

Step-by-step explanation:

Here, the given expression is,

7x − one over two (8x + 4) = 6

⇒

So, the steps which are involved in solving the given equation are as follows,

Step 1 : By distributive property,

Step 2 : Combine like terms,

Step 3 : Adding 2 on both sides,

Step 4 : Combine like terms,

Step 5 : By division property of equality,

Thus, by the above explanation it is clear that step 3 was made error because 2 is not added to the right side of the equation.

answer: 40392

step-by-step explanation:

10098 x 4 = 40392

the correct option is:

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

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!
