Question 530653: how to factor 3x^2-22x+40
Answer by algebrahouse.com(1659) (Show Source): You can put this solution on YOUR website!
3x² - 22x + 40
= 3x² - 12x - 10x + 40 {factoring by grouping, split -22x into -12x and -10x}
= 3x(x - 4) - 10(x - 4) {factored 3x out of 1st two terms and -10 out of last two}
= (3x - 10)(x - 4) {factored x - 4 out of the two terms}
