The simplified form of the expression, 6x²-23x+15, is (6x - 5)(x - 3)
The simplified form of the expression, x²-9, is (x + 3)(x - 3)
From the question, we are to simplify the given expression by factoring
The given expression is
6x² - 23x + 15
Factoring
6x² - 23x + 15
6x² - 18x - 5x + 15
6x(x - 3) -5(x - 3)
(6x - 5)(x - 3)
∴ The simplified form of the expression is (6x - 5)(x - 3)
We are to simplify
x² - 9
By difference of two squares, we have that
a² - b² = (a + b)(a - b)
x² - 9 can be expressed as
x² - 3²
Thus,
Using difference of two squares
x² - 3² = (x + 3)(x - 3)
Hence, the simplified form of the expression is (x + 3)(x - 3)
