Solve -i^2+6i^2

$$- i ^ { 2 } + 6 i ^ { 2 }$$

Evaluate

$$-5$$

Solution Steps

Calculate i to the power of 2 and get -1.

$$-\left(-1\right)+6i^{2}$$

The opposite of -1 is 1.

$$1+6i^{2}$$

Calculate i to the power of 2 and get -1.

$$1+6\left(-1\right)$$

Multiply 6 and -1 to get -6.

$$1-6$$

Subtract 6 from 1 to get -5.

$$-5$$

Real Part

$$-5$$

Solution Steps

Calculate i to the power of 2 and get -1.

$$Re(-\left(-1\right)+6i^{2})$$

The opposite of -1 is 1.

$$Re(1+6i^{2})$$

Calculate i to the power of 2 and get -1.

$$Re(1+6\left(-1\right))$$

Multiply 6 and -1 to get -6.

$$Re(1-6)$$

Subtract 6 from 1 to get -5.

$$Re(-5)$$

The real part of -5 is -5.

$$-5$$
