Answer :
- 144
Given :
- x = 3
- y = -2
- (2x - 3y)²
To find :
- the value of (2x - 3y)²
Solution :
⇒ Let's write the value of x and y.
= (2x - 3y)²
= (23 - 3-2)²
= [(2 × 3) (- 3 × -2)]²
⇒ Let's Evaluate now.
= [(6 - 3 × -2)]²
= [(6 - (-6)]²
= [6 + 6]
= 12²
= 144
Therefore, the value of the following equation is 144.
