Question

The question is the one on the sheet​

Answer 1

Total area

`= ({5x}^(2) - 6x + 4) + ( {15x}^(2) + 8x + 2)`

`= {5x}^(2) - 6x + 4 + 15 {x}^(2) + 8x + 2`

`= ( {5x }^(2) + {15x}^(2) ) + ( - 6x + 8x) + (2 + 4)`

`= {20x}^(2) + 2x + 6`

Answer 2

Explanation:

Total area will be sum of two areas

5x²-6x+4 + 15x²+8x+2

20x²+2x+6
