Answer 2

QUESTION:

Co-Effecient of x² in (x²- 1)(4 + 3x²)

a. 1

b. 5

c. (-8)

d. 9

ANSWER:

The Co-Effecient of x^2 in (x^2 + 1)(4 + 3x^2) is 1.

The Option a is Right..

REASON:

$= > ( {x}^{2} - 1)(4 + {3x}^{2} ) \\ \\ = > {4x}^{2} + {3x}^{4} - 4 - {3x}^{2} \\ \\ = > {x}^{2} + {3x}^{4} - 4$

As x^2 does not have a Constant, we can Conclude that the Co-Efficient of x^2 is 1.

HOPEFULLY, IT'S HELPFUL...
