Product of polynomials can be done by distribution of multiplication over addition. The product of  (2x - 3)(2x^2 + 7x  - 1) is 4x^3 + 8x^2 -23x + 3

<h3>What is distributive property of multiplication over addition?</h3>

Suppose a, b and c are three numbers. Then we have:

a(b + c) = a\times b + a\times c

(a(b+c) means a multiplied to (b+c). The sign of multiplication is usually hidden when using symbols and both quantities which are in multiplication are written together without space)

The product result of the given expression is

(2x - 3)(2x^2 + 7x  - 1)  = 2x(2x^2 + 7x  - 1) -3(2x^2 + 7x  - 1) \\(2x - 3)(2x^2 + 7x  - 1)  = 4x^{1+2} + 14x^2 -2x - 6x^2 - 21x + 3\\(2x - 3)(2x^2 + 7x  - 1)   = 4x^3 + (14 -6)x^2 + (-2 -21)x + 3\\(2x - 3)(2x^2 + 7x  - 1)   = 4x^3 + 8x^2 -23x + 3

It is because when bases are same and there is multiplication, then powers add up, so we have: a^b \times a^c = a^{b+c}

Also, we've

(-ve \times (+ve) = -ve\\(-ve) \times (-ve) = +ve\\(+ve) \times (+ve) = +ve\\(+ve) \times (-ve) = -ve

where -ve, +ve are sign of operands and result.

That's why 2 \times -1 = -2

Thus,

The product of   (2x - 3)(2x^2 + 7x  - 1)  is 4x^3 + 8x^2 -23x + 3

Which relation is a function? (look at image below)
Dimas [21]

Answer:

Bottom Right Graph (Absolute Value)

General Formulas and Concepts:

  • Vertical Line Test

Step-by-step explanation:

When we apply the VLT to the 4 different graphs, we see that the only graph that actually passes the VLT is the absolute value graph. Therefore, that is our answer (none of the other graphs pass the VLT).
