Answer:
(x − 6i) (x + 6i)
Step-by-step explanation:
Using real numbers, x² + 36 is already simplified.
Using imaginary numbers:
x² + 36
x² − 36i²
(x − 6i) (x + 6i)
Answer:
When x = 3, the solutions to the expressions are–20 and –20
Step-by-step explanation:
–4(3) – 8 Multiply
-12 - 8 Subtract
-20
-2(3 + 1) - 2(3 + 3) Simplify in the parentheses
-2(4) - 2(6) Multiply
-8 - 12 Subtract
-20
