Prove the following limit LIM (x →∞) x & # 178; - 4 / 2x & # 178; + x = 1 / 2 by definition
LIM (3x & # 179; - 2x & # 178; - x + 2) x tends to 3,
A:
The limit of this polynomial can be directly substituted into the evaluation
Original formula = 3 * 27-2 * 9-3 + 2
=81-18-1
=80-18
=62
The limit is 62
The following expressions are correct: () a.4x & # 178; + 8x + 3 = (2x-3) (2x-1) b.4x & # 178; - 13X + 3 = (x-3) (4x + 1)
C.6x²+7x-10=(6x-5)(x+2) D.6x²+13x-10=(2x+5)(3x-2)
The following are correct: (c)
A.4x²+8x+3=(2x-3)(2x-1) B.4x²-13x+3=(x-3)(4x+1)
C.6x²+7x-10=(6x-5)(x+2) D.6x²+13x-10=(2x+5)(3x-2)
