Question

Which expression is equivalent to (5g^4+5g^3-17g^2+6g)-(3g^4+6g^4-7g^2-12/g+2

Answer 1

Answer

$=(5 g^4+5 g^3-17 g^2+6 g)-(3 g^4+6 g^4-7 g^2-\frac{12}{g}+2)$

Opening the brackets and adding and subtracting the like terms

$=5 g^4+5 g^3-17 g^2+6 g-3 g^4-6 g^4+7 g^2+\frac{12}{g}-2\\\\ =5 g^4-9 g^4 +5 g^3-17 g^2+7 g^2+6 g +\frac{12}{g}-2\\\\ = -4 g^4 + 5 g^3 -10 g^2+6 g+\frac{12}{g}-2$

This is equivalent expression of the expression given.

$= -4 g^4 + 5 g^3 -10 g^2+6 g+\frac{12}{g}-2$

Answer 2

My Answer would be 7, or -4g^5 + 5g^4 - 10g^3 + 6g^2 - 2g +12/g

the second answer is a fraction over g

if this is wrong I'm sorry
