Will give ! jerry solved this equation:  3 ( x − 1 4 ) = 13 6 1. 3x − 3 4 = 13 6 2. 3x − 3 4 + 3 4 = 13 6 + 3 4 3. 3x = 26 12 + 9 12 4. 3x = 35 12 5. ( 3 1 ) 3 1 x = 35 12 ( 3 1 ) 6. x = 105 12 in which step did jerry make an error? a) in step 2, he should have subtracted 3/4 from both sides. b) in step 3, he should have found an lcd of 10. c) in step 4, he should have subtracted 9 from 26. d) in step 5, he should have multiplied both sides by 1.3

the answer is the fourth option or D

Step-by-step explanation:

option D

Step-by-step explanation:

Jerry solved this equation: 

In the first step , she multiplied 3 inside the parenthesis

1.

In step 2, 3/4 is added on both sides

2.

In step 3, we take LCD 12

3.

In step 4, add the fractions

4.

Here, 3 or 3/1 are same.

In step 5, to remove 3/1 we multiply both sides by 1/3.

Instead of multiplying 1/3 , Jerry made an error by multiplying 3/1

In step 5, he should have multiplied both sides by 1/3

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!
