Explain why (2 + 3i)(2 – 3i) is a REAL number.

Complex Number, Real Part, Imaginary Part. 3 + 2i, 3, 2. 5, 5, 0, Purely Real. −6i, 0, − ... Example: add the complex numbers 3 + 5i and 4 − 3i ... Example: (3 + 2i)(1 + 7i) = (3×1 − 2×7) + (3×7 + 2×1)i = −11 + 23i. Why Does That Rule Work

We used the distributive property to multiply a real number by a complex number.(2 − 16i) = (5 − i)(a + bi) = 5a + 5bi −ai + b = (5a + b) +

Step-by-step explanation:

step-by-step explanation:

two pairs of adjacent sides are of equal length. this implies that one diagonal divides the kite into congruent triangles, and so the angles between the two pairs of equal sides are equal in measure. it also implies that the diagonals are perpendicular.
