What is the factorization of 3x2 – 8x + 5?

For this case we must factor the following expression:

We rewrite the middle term as a sum of two terms whose product is

And whose sum is

These numbers are:

-5 and -3

So:

We factor the maximum common denominator of each group:

We take common factor

(f - g)(x) = 5x^3 - 3

step-by-step explanation:

rearrange these functions vertically, with like terms in separate columns:

f(x) = 5x^3 - 2

g(x) =         +1

now subtract, column by column:

(f - g)(x) = 5x^3 - 3

step-by-step explanation:

hans did not square the 40-unit side; he merely multiplied it by 2.   incorrect.
