Answer:

6x² - 19x + 10

Step-by-step explanation:

Given

(3x - 2)(2x - 5)

Each term in the second factor is multiplied by each term in the first factor, that is

3x(2x - 5) - 2(2x - 5) ← distribute both parenthesis

= 6x² - 15x - 4x + 10 ← collect like terms

= 6x² - 19x + 10

27. (-2 + √-8) + (5 - √-50) standard form ?​
marin [14]

We can break this down by removing the parenthesis first:

-2 + \sqrt{-8} + 5 - \sqrt{-50}

In order to continue, you have to simplify the square roots by factoring it and taking out i:

-2 + 2i\sqrt{2} + 5 - 5i\sqrt{2}

Combine like terms:

-3 - 3i\sqrt{2} <-- that's the answer

Hope I helped :)
