Expand and simplify the following
√3 (√3 - 1)
√5 (√10 + √2)

B

Step-by-step explanation:

is a quadratic formula where a = 10, b = 3, and c = -2

⇒ 10x² + 3x - 2 = 0

Now let's look at the options provide and put them in standard form:

a) 10x² = 3x + 2

   10x² - 3x - 2 = 0

This is NOT the same as our answer above

b) 2 = 3x + 10x²

   0 = 10x² + 3x - 2

This IS the same as our answer above!!!

No need to check C and D because we already found the answer.
