The polynomial 2x3 − 5x2 + 4x − 10 is split into two groups, 2x3 + 4x and −5x2 − 10. The GCFs of each group is then factored out . What is the common binomial factor between the two groups after their GCFs have been factored out?
a)2x + 5
b)2x − 5
c)x2 − 2
d)x2 + 2

Answer:
2x³ - 5x² + 4x - 10
(2x³ + 4x) + (-5x² - 10)
2x(x² + 2) - 5(x² + 2) = Answer is Choice D. Step-by-step explanation:
2x³ - 5x² + 4x - 10 (2x³ + 4x) + (-5x² - 10) 2x(x² + 2) - 5(x² + 2) = Answer is Choice D. x² + 2

If an angle is 70 degrees and there is an angle vertical to it, then that other angle also equals 70 degrees. Therefore, if angle X equals 40 degrees, then angle Y also equals 40 degrees. Hope this helps.
Answer:
No solutions
Step-by-step explanation:
4(2x-3)=2(4x-6)
Same components are present on both sides of equal sign, therefore NO SOLUTIONS are possible.
It should be a whole number.
