Answer:
D. 2(x - 1)(x – 3)
Step-by-step explanation:
4(x2 – 2x) – 2(x2 – 3)
We would first of all expand the expression given
This becomes
= 4x2 - 8x - 2x2 + 6
Rearrange to enable us simplify
4x2 - 2x2 - 8x + 6
= 2x2 - 8x + 6
Factorize
2 (x2 - 4x + 3)
factorizing further using the factors of 3 that add up to -4
2(x2 - x - 3x + 3)
pick out the common factors
2(x(x-1) -3(x-1)
2(x-1)(x-3)
Option D. 2(x - 1)(x – 3) is right
Answer:
8
Step-by-step explanation:
Answer:
x = 24.8
Step-by-step explanation:
2x + 12.8 + 117.6 = 180
Then solve.
2x + 130.4 = 180
2x = 4.6
x = 24.8
Smaller x = -1.33 and larger x = -1
Gm = √a*b for two numbers
hence gm = √6*42 = 2√63 = 15.87
