What is the sum (Two-fifths x + Start Fraction 5 over 8 End Fraction) + (one-fifth x minus one-fourth)? Three-fifths x + Start Fraction 1 over 8 End Fraction Three-fifths x + Start Fraction 3 over 8 End Fraction Three-fifths x + Start Fraction 5 over 8 End Fraction Three-fifths x + Start Fraction 7 over 8 End Fraction

3/5x + 3/8

Three-fifths x + Start Fraction 3 over 8

Step-by-step explanation:

Sum of :

(2/5x + 5/8) + (1/5x - 1/4)

Open the bracket :

2/5x + 5/8 + 1/5x - 1/4

Collect like terms :

2/5x + 1/5x + 5/8 - 1/4

3/5x + (5 - 2)/8

3/5x + 3/8

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!
