Answer: −3x²−15x−30
Step-by-step explanation: use Square of Sum (a+b)²=a²+2ab+b²
−3(x²+2x×3+3²)-3+3x
−(3x² +18x+27)−3+3x
−3x²−18x−27−3+3x
−3x²+(−18x+3x)+(−27−3)
−3x²−15x−30
Hope this helps, now you know the answer and how to do it. Stay healthy and safe and HAVE A BLESSED AND WONDERFUL DAY! :-)

Topic : Linear equations in two variables.
Given :
- 2x - y = 3 ––– (i)
- - x - y = 3 ––– (ii)
Solution :
Now,
(i) – (ii)




Now, substituting the value of x in Eq (i) :




Therefore,
- <u>The value of x = 0 and y = -3</u>
