Pablo and Golden are sharing a vegetable garden. The total area of the garden is represented by the expression 5x2−3x+10
. The amount of garden area that belongs to Golden is represented by the expression 2x2+4x−2
. What is the difference in area of the garden that belongs to Pablo?

To find the area of the garden that belongs to Pablo, we need to subtract the area that belongs to Golden from the total area of the garden.

  1. Total Area of the Garden:
    \[ 5x^2 - 3x + 10 \]

  2. Area that Belongs to Golden:
    \[ 2x^2 + 4x - 2 \]

  3. Area that Belongs to Pablo:
    \[ \text{Area of Pablo} = \text{Total Area} - \text{Area of Golden} \] \[ \text{Area of Pablo} = (5x^2 - 3x + 10) - (2x^2 + 4x - 2) \]

Now, we will distribute the negative sign and combine like terms:

\[ = 5x^2 - 3x + 10 - 2x^2 - 4x + 2 \]

Now, combine like terms:

  • For \(x^2\) terms: \[5x^2 - 2x^2 = 3x^2\]

  • For \(x\) terms: \[-3x - 4x = -7x\]

  • For constant terms: \[10 + 2 = 12\]

Putting it all together, we get:

\[ \text{Area of Pablo} = 3x^2 - 7x + 12 \]

Therefore, the area that belongs to Pablo is:

\[ 3x^2 - 7x + 12 \text{ square feet.} \]
