given that a=4,b=-2 and c=3

Calculate the value of a^2-bc/b+c
answer=22

that's right.

To calculate the value of the expression a^2 - bc / (b + c), let's substitute the given values: a = 4, b = -2, and c = 3.

1. Replace the variables in the expression with their corresponding values:
a^2 - bc / (b + c)
-> (4)^2 - (-2)(3) / (-2 + 3)

2. Simplify the expression:
-> 16 - (-6) / 1
-> 16 + 6 / 1
-> 22 / 1

3. Divide the numerator by the denominator:
-> 22 / 1
-> 22

Therefore, the value of the expression a^2 - bc / (b + c) when a = 4, b = -2, and c = 3 is 22.
