When A=3,b= -1 what is the value of Ab-b2
Does b2 mean -b squared?
A = 3
b = -1
Ab-b^2 = (3)*(-1)^2 = ?
To find the value of Ab - b^2 when A = 3 and b = -1, we can substitute these values into the expression.
Given:
A = 3
b = -1
Substituting these values:
Ab - b^2 = (3)(-1) - (-1)^2
Simplifying the expression:
= -3 - 1
= -4
Therefore, when A = 3 and b = -1, the value of Ab - b^2 is -4.
