The correct answer is (4x-5)(3-6x).
To factor the expression, we need to find two numbers that multiply to give -24 and add to give 42. These numbers are -3 and 8.
Then, we can write the expression as:
-24x^2 + 42x - 15 = -3(8x^2 - 14x + 5)
Next, we can factor the quadratic expression inside the parentheses:
8x^2 - 14x + 5 = (4x - 5)(2x - 1)
Substituting this back into the original expression, we get:
-24x^2 + 42x - 15 = -3(4x - 5)(2x - 1)
Finally, we can simplify this expression by distributing the -3:
-24x^2 + 42x - 15 = (4x - 5)(-6x + 3) = (4x - 5)(3 - 6x)
Which of these represents −24x2+42x−15
in factored form?
