Solve (b 7) (2b 7)=44

Evaluate

(b \times 7) (2 b \times 7) = 44

Remove the parentheses

b \times 7 \times 2 b \times 7 = 44

Multiply

More Steps

98 b^{2} = 44

Divide both sides

\frac{98 b ^{2}}{98} = \frac{44}{98}

Divide the numbers

b^{2} = \frac{22}{49}

Take the root of both sides of the equation and remember to use both positive and negative roots

b = \pm \frac{22}{49}

Simplify the expression

b = \pm \frac{22}{7}

Separate the equation into 2 possible cases

b = \frac{22}{7} b = - \frac{22}{7}

Solution

b_{1} = - \frac{22}{7}, b_{2} = \frac{22}{7}

Alternative Form

b_{1} \approx - 0.670059, b_{2} \approx 0.670059
