Solve m^22-1900005

Question

Simplify the expression

2 m^{2} - 1900005

Evaluate

m^{2} \times 2 - 1900005

Solution

2 m^{2} - 1900005

Show Solution

m_{1} = - \frac{3800010}{2}, m_{2} = \frac{3800010}{2}

Alternative Form

m_{1} \approx - 974.680717, m_{2} \approx 974.680717

Evaluate

m^{2} \times 2 - 1900005

To find the roots of the expression,set the expression equal to 0

m^{2} \times 2 - 1900005 = 0

Use the commutative property to reorder the terms

2 m^{2} - 1900005 = 0

Move the constant to the right-hand side and change its sign

2 m^{2} = 0 + 1900005

Removing 0 doesn't change the value,so remove it from the expression

2 m^{2} = 1900005

Divide both sides

\frac{2 m ^{2}}{2} = \frac{1900005}{2}

Divide the numbers

m^{2} = \frac{1900005}{2}

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

m = \pm \frac{1900005}{2}

The product of roots with the same index is equal to the root of the product

1900005 \times 2

Calculate the product

3800010

\frac{3800010}{2 \times 2}

When a square root of an expression is multiplied by itself,the result is that expression

\frac{3800010}{2}

m = \pm \frac{3800010}{2}

Separate the equation into 2 possible cases

m = \frac{3800010}{2} m = - \frac{3800010}{2}

Solution

m_{1} = - \frac{3800010}{2}, m_{2} = \frac{3800010}{2}

Alternative Form

m_{1} \approx - 974.680717, m_{2} \approx 974.680717
