Solve m^2 2m-3 - ScanMath

Question

Simplify the expression

2 m^{3} - 3

Evaluate

m^{2} \times 2 m - 3

Solution

More Steps

Evaluate

m^{2} \times 2 m

Multiply the terms with the same base by adding their exponents

m^{2 + 1} \times 2

Add the numbers

m^{3} \times 2

Use the commutative property to reorder the terms

2 m^{3}

2 m^{3} - 3

Show Solution

m = \frac{3 12}{2}

Alternative Form

m \approx 1.144714

Evaluate

m^{2} \times 2 m - 3

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

m^{2} \times 2 m - 3 = 0

Multiply

More Steps

Multiply the terms

m^{2} \times 2 m

Multiply the terms with the same base by adding their exponents

m^{2 + 1} \times 2

Add the numbers

m^{3} \times 2

Use the commutative property to reorder the terms

2 m^{3}

2 m^{3} - 3 = 0

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

2 m^{3} = 0 + 3

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

2 m^{3} = 3

Divide both sides

\frac{2 m ^{3}}{2} = \frac{3}{2}

Divide the numbers

m^{3} = \frac{3}{2}

Take the 3 -th root on both sides of the equation

3 m^{3} = 3 \frac{3}{2}

Calculate

m = 3 \frac{3}{2}

Solution

More Steps

Evaluate

3 \frac{3}{2}

To take a root of a fraction,take the root of the numerator and denominator separately

\frac{3 3}{3 2}

Multiply by the Conjugate

\frac{3 3 \times 3 2 ^{2}}{3 2 \times 3 2 ^{2}}

Simplify

\frac{3 3 \times 3 4}{3 2 \times 3 2 ^{2}}
