Question

2y^4-8y^3+y^2 what’s the answer using distributive property

Answer 1

Step-by-step explanation:

STEP

1

:

Equation at the end of step 1

(2 • (y4)) - 23y2

STEP

2

:

Equation at the end of step

2

:

2y4 - 23y2

STEP

3

:

STEP

4

:

Pulling out like terms

4.1 Pull out like factors :

2y4 - 8y2 = 2y2 • (y2 - 4)

Trying to factor as a Difference of Squares:

4.2 Factoring: y2 - 4

Theory : A difference of two perfect squares, A2 - B2 can be factored into (A+B) • (A-B)

Proof : (A+B) • (A-B) =

A2 - AB + BA - B2 =

A2 - AB + AB - B2 =

A2 - B2

Note : AB = BA is the commutative property of multiplication.

Note : - AB + AB equals zero and is therefore eliminated from the expression.

Check : 4 is the square of 2

Check : y2 is the square of y1

Factorization is : (y + 2) • (y - 2)

Final result :

2y2 • (y + 2) • (y - 2)

Answer 2

Answer:

Conductivity tests of electricity through various liquid substances are done by placing electrodes at either end of a tank of the solution. While Specific Conductance is a measure of how well water can conduct an electrical current. Conductivity increases with increasing amount and mobility of ions.
