Using the quadratic equation we get:

Factoring out 2 we get

Factoring out the imaginary number:

So b.
3.95*10^9 move the decimal to the left untill it is in between the last ans 2nd to last number
Answer:
The answer to this question is dilating the figure by a scale factor of one half.
You have to first make like terms

**you want the denominator to be 21
Answer:
(6x + 5)(7x² - 6)
Step-by-step explanation:
Factor the first/second and third/fourth term
42x³ + 35x² - 36x - 30
= 7x²(6x + 5) - 6(6x + 5) ← factor out (6x + 5) from each term
= (6x + 5)(7x² - 6)
