Answer:
3x^2 - 4x - 9
Step-by-step explanation:
Subtract the sum of 4X2 + 6X + 3 and 2x2 + 4x+ 9 from
9x2 + 6x + 3
STEP 1
= 4x^2 + 6x +3 + 2x^2 + 4x + 9
= 4x^2 + 2x^2 + 6x + 4x + 3 + 9
= 6x^2 + 10x + 12
STEP 2
= 9x^2 + 6x + 3 - [ 6x^2 + 10x + 12 ]
= 9x^2 + 6x + 3 - 6x^2 - 10x - 12
= 9x^2 - 6x^2 + 6x - 10x + 3 - 12
= 3x^2 - 4x - 9
this is the correct answer
