¿Cuál es el valor numérico del siguiente polinomio para x=2? P(x) = x3 + 5x2 - 4x + 1
=
-
P(2) = 23 +5.22 – 4.2+1
P(2) = 8 +5.4-4-2 +1
P(2) = 8 + 20 - 8+1

d. 8

step-by-step explanation:

the given radical expression is:

we can rewrite this as:

we express as square numbers to get;

the exponents will now cancel out to give.

the correct answer is d

the correct answer is $7.38

step-by-step explanation:

the image is given below

since the options are not given so we draw it from the equation

the given equation is

y = (x-1) (x+4)

y = y² + 3x - 4

the above equation is a quadratic equation which will have two roots. if we draw the graph for it, it will look like this
