Answer:
a = -86.
Step-by-step explanation:
By the Factor Theorem, if x + 4 is a factor then P(-4) = 0, so:
P(-4) = 2(-4)^3 - 11(-4)^2 + a(-4)- 40 = 0
-128 - 176 - 4a - 40 = 0
-4a = 128 +176 + 40
-4a = 344
a = -86.
Answer:
yes, i think it is
Step-by-step explanation:
Answer:
This is true
Step-by-step explanation:
Take for example 10=5x, you would divide both sides by 5 without changing anything to the equation.
In a case like 5=0x, you can't divide both sides by 0, so the solution is undefined.
