Rewrite the expression 2-bx2<56 to get the variable b alone on one side of the equation.

b >-54/x^2

Step-by-step explanation:

2-bx^2<56

Subtract 2 from each side

2-2-bx^2<56-2

-bx^2 <54

Divide by -1, remembering to flip the inequality

bx^2 > -54

Divide each side by x^2

bx^2/x^2 > -54/x^2

b >-54/x^2

b > -54/x²

Step-by-step explanation:

2 - bx² < 56

2 - 56 < bx²

-54 < bx²

-54/x² < b

b > -54/x²
