The square of a is 4, the square of B is 9, and ab is less than 0_ The value of B

The square of a is 4, the square of B is 9, and ab is less than 0_ The value of B


A = 2, B = - 3 or a = - 2, B = 3



Given that the square of a is 9 and the absolute value of B is 3, find the sum of a + B


From the square of a equals 9, we can get a = 3 or - 3
From the absolute value of B equal to 3, we can get b = 3 or - 3
A=3,B=3,A+B=6
A=3,B=-3,A+B=0
A=-3,B=3,A+B=0
A=-3,B=-3,A+B=-6
So the result is - 6,0,6



If - 1


1 / A
