By the remainder theorem 8x^2 + 4x - 3 when divided by 2x - 1 is
8(1/2)^2 + 4(1/2) - 3 = 2 + 2 - 3 = 1 answer
Answer:
factored form
Step-by-step explanation:
example
(x + 2)(x + 3) ← is an expression in factored form
= x² + 5x + 6 ← in expanded form
5 ft but I don’t know why I just like 5
This is a simple problem! So let’s start. The rule a negative and a negative makes a positive plays a role in here so then we can switch it to -6+9 now subtract 9 to 6 and you get 3. That will be your answer. You can switch the numbers around to make it easier that what I like to do. For example, instead of having -6+9 you could instead do 9-6!
Hope this helps!
If I’m wrong say it in comments I don’t want it to harm others.
-5x-10=10
-5x=20(added ten to both sides)
x=-4(divided by -5 on both sides)
