Question

Which of these is a factor in this expression- 7z^4-5+10(y^3+2). Choices- A- 7z^4-5, B- 10(y^3+2) C = -5+10(y^3+2) D= (y^3+2)

Answer 1

Answer:

D. ($y^{3}$ + 2)

Step-by-step explanation:

A factor of an expression can either be in the form of an algebraic expression, alphabet or number. In the question, the given expression can be written as;

7$z^{4}$ - 5 + 10$y^{3}$ + 20

Factorizing the expression gives;

7$z^{4}$ - 5 + 10($y^{3}$ + 2)

Therefore, it would be observed that the factor in the expression is;

($y^{3}$ + 2)
