Devin was explaining his first step in factoring, but made an error in his explanation.
Factor: 3p^2-10p+8
Devin said, "I know a=3,b=10,and c=8. Now, I need ti find the factors of 24 that add to 10."
What was the error in his thoughts process?
clearly
b = -10
The error in Devin's thought process is that he incorrectly identified the values of a, b, and c in the quadratic expression 3p^2-10p+8.
In the expression 3p^2-10p+8, the value of a is actually the coefficient of the p^2 term, which is 3.
The value of b is the coefficient of the p term, which is -10.
And the value of c is the constant term, which is 8.
Instead of using the correct values, Devin mistakenly identified a as 3, b as 10, and c as 8. This error led him to find the factors of 24 that add to 10, which is not relevant to factoring the given expression.
