Hello there!
(x - 3)(x + 9) = -27
x² + 6x - 27 = -27
x² + 6x = -27 + 27
x² + 6x = 0
Factorize
x(x + 6) = 0
Now all we have to do is set the factors equal to 0
x = 0 or x+6 = 0
x = 0 or x = -6
Answer : x = 0 or x = -6
I don't know what the options they give you. But if you see 0 or 6 choose it.
I hope this help!
Answer:
where is the question.
So basically rational numbers are numbers with decimals that are not random
ex) 3.66666666, 4.040404040, 3.5645645645646
the decimals are at a fixed order
Irrational is random decimals that makes it look weird
ex)3.141592643, 5. 782759453, 8.825928342
hope that answers your question
