Simplifying (-7i)(-7i) = x Remove parenthesis around (-7i) -7i(-7i) = x Remove parenthesis around (-7i) -7i * -7i = x Reorder the terms for easier multiplication: -7 * -7i * i = x Multiply -7 * -7 49i * i = x Multiply i * i 49i2 = x Solving 49i2 = x Solving for variable 'i'. Move all terms containing i to the left, all other terms to the right. Divide each side by '49'. i2 = 0.02040816327x Simplifying i2 = 0.02040816327x Combine like terms: 0.02040816327x + -0.02040816327x = 0.00000000000 i2 + -0.02040816327x = 0.00000000000 The solution to this equation could not be determined.
