The question follows the special product rule of polynomials.
(a-b)(a+b) = a^2 - b^2
From the given, (3-2i)(3+2i), then the answer will be 3^2 - (2i)^2
simplifying the answer:
9 - 4i^2
Take note that i = square root of -1
Then, i^2 = -1
So, 9 - (4 * -1)
= 9 - -4
= 13.
So the answer is 13.
Answer:
497
Step-by-step explanation:
350*1.42
A = 1/2 b h where b = 3.4 cm and h = 8 cm
A = 1/2 (3.4)(8)
A = 13.6 cm^2
Answer: 13.6 cm^2
