P(x)=x^2-6x+5[/tex]


\\ \sf\longmapsto P(4)


\\ \sf\longmapsto 4^2-6(4)+5


\\ \sf\longmapsto 16-24+5


\\ \sf\longmapsto -8+5


\\ \sf\longmapsto -3

The correct option is a.

P(4) is equal to -3.

To find P(4), follow these steps:

Step 1: Start with the given polynomial:

P(x) = x^2 - 6x + 5

Step 2: Replace x with 4 in the polynomial:

P(4) = (4)^2 - 6(4) + 5

Step 3: Calculate the values inside the parentheses and perform the arithmetic operations:

P(4) = 16 - 24 + 5

Step 4: Continue simplifying:

P(4) = 16 - 24 + 5

P(4) = (16 - 24) + 5

P(4) = (-8) + 5

Step 5: Finally, add the two values:

P(4) = -8 + 5

Step 6: Perform the addition:

P(4) = -3

So, The answer is -3.
