Answer:

[tex]B1 = \frac{2A-(h*B2)}{h}[/tex]

or

[tex]B1=\frac{2A}{h} - B2[/tex]

Step-by-step explanation:

FOIL

(1/2)h*B1+ (1/2)h*B2=A

subtract the B2 term

(1/2)h*B1 = A- (1/2)h*B2

multiply by 2

h*B1 = 2A - h*B2

divide by h

[tex]B1 = \frac{2A-(h*B2)}{h}[/tex]

or

[tex]B1=\frac{2A}{h} - B2[/tex]
