Answer with explanation:
→y²+5y+6
=y²+3 y+2 y+6
=y×(y+3)+2×(y+3)
=(y+2)(y+3)
→y² -3 y-10
=y² -5 y+2 y -10
=y×(y-5)+2×(y-5)
=(y+2)(y-5)
Which monomial is a perfect cube? 49p9q3r24 81p12q15r12 121p9q3r6 343p6q21r6.
1 answer:
The monomial is a perfect cube is .
Perfect cubes are the numbers that are the triple product of the same number.
We have to determine
Which monomial is a perfect cube?
A perfect cube monomial must have three identical roots, such that the product of the roots equals the perfect square monomial.
It must be possible for the coefficient of a perfect cube monomial to be written in the form n3, where n equals the cube root of the coefficient.
A perfect cube monomial must have exponents on the variables.
Then
The monomial is a perfect cube is;
Hence, the monomial is a perfect cube is .
