Express the product of 2x squared plus 6x -8 and x+3 in standard form
NeTakaya

ANSWER

The standard form is:

2 {x}^{3}  + 12 {x}^{2}   + 10x - 24

EXPLANATION

The given product is

(2 {x}^{2}  + 6x - 8)(x + 3)

We expand using the distributive property to get:

x(2 {x}^{2}  + 6x - 8) + 3(2 {x}^{2}  + 6x - 8)

Expand the parenthesis;

2 {x}^{3}  + 6 {x}^{2}  - 8x + 6 {x}^{2}  + 18x - 24

This simplifies to

2 {x}^{3}  + 12 {x}^{2}   + 10x -24

Standard form is when the polynomial is arranged in decreasing powers of x.

DIA [1.3K]

Answer:

A 3/30=x/12

Step-by-step explanation:

According to the recipe,

For 2 batches, 3 cups of flour required.

One batch has 15 mix rolls

Then 2 batches will have 2 (15) = 30 rolls

Each person gets one roll, so 3 cups of flour is required for 30 people.

The quanity of flour is proportional to the number of people.

Let x be the quantity of flour required for 12 people.

ELEN [110]
I'm not entirely sure what you're asking, but I believe the answer to your question can be solved by dividing both 6 and 24 by 6 which would give you 1/4, making your answer 4. Hope this helps!
