Find the product. (y - 2bs^2) (y + 3bs^2) Enter the correct answer.

Vikentia [17]

Answer:

y² + bs²y - 6b²s⁴

General Formulas and Concepts:

Expand by FOIL (First Outside Inside Last)
Exponent Power Rule: $(b^m)^n=b^{mn}$

Step-by-step explanation:

Step 1: Define expression

(y - 2bs²)(y + 3bs²)

Step 2: FOIL

First: y · y = y²
Outside: y · 3bs² = 3bs²y
Inside: -2bs² · y = -2bs²y
Last: -2bs² · 3bs² = -6b²s⁴

Step 3: Simplify

Combine: y² + 3bs²y - 2bs²y - 6b²s⁴
Combine like terms: y² + bs²y - 6b²s⁴

1-7x - 7=15 please answer and show how you got answer please

zlopas [31]

Answer:

x=-3

Step-by-step explanation:

1-7x-7=15

We move all terms to the left:

1-7x-7-(15)=0

We add all the numbers together, and all the variables

-7x-21=0

We move all terms containing x to the left, all other terms to the right

-7x=21

x=21/-7

x=-3
