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

Solve. a-5/a+4 = 5/4 a = 0 a = -1 a = -9 a = -40

Degger [83]

Answer:

-40=a

Step-by-step explanation:

( a-5)/(a+4) = 5/4

Multiply by (a+4) on each side

( a-5)/(a+4) * (a+4) = 5/4 (a+4)

a-5 = 5/4 (a+4)

Multiply by 4 on each side to clear the fractions

4(a-5) = 5/4*4 (a+4)

4(a-5) = 5 (a+4)

Distribute

4a -20 =5a +20

Subtract 4a from each side

4a -4a -20 = 5a-4a +20

-20 =a+20

Subtract 20 from each side

-20-20 =a+20-20

-40=a
