Perform The Indicated Operation On Polynomials Using The Law Of Exponents, 1. 3x (X2 - 5x+7), 2. (X

Perform the indicated operation on polynomials using the law of exponents 1. 3x (x2 - 5x+7)
2. (x + 3)(x + 5)
3. 5xyº (2x’y - 3x + 4y)
4. 12x4-16x + 8x + 4x*
5. (x+6x? + 11x + 6) + (x-3)

 

Answer:

1.) 3x (x2 - 5x+7) = - 9x2 + 21x

2.) (x + 3)(x + 5) = x2 + 8 x + 15

3.) 5xyº (2x’y - 3x + 4y) = 10x(2y+y  3  x 4 )

4.) 12x4-16x + 8x + 4x* = 4(12 - x)

5.) (x+6x? + 11x + 6) + (x-3) = 19x + 3
