Answer:
15x - 21x² + 12
Step-by-step explanation:
(3x - 6)(2 X 2 - 7x + 1) = (3x - 6)(4 - 7x + 1)
= (3x - 6)(5 - 7x)
= (3x X 5) + (3x X -7x) + (-6 X 5) + (-6 X -7)
= 15x - 21x² - 30 + 42
= 15x - 21x² + 12
Answer:
(3x-6)(2x² -7x+1)
= 6x³ - 33x² + 45x - 6
Step-by-step explanation:
(3x-6)(2x² -7x+1)
To find the product of this we will expand the equation by multiplying each element in one bracket with the other bracket.
(3x-6)(2x² -7x+1)
Expand
(3x)(2x² - 7x + 1) (-6)(2x² - 7x + 1)
Opening the bracket (multiple)
6x³ - 21x² + 3x - 12x² + 42x - 6
Collect like terms
= 6x³ - 21x² - 12x² + 3x + 42x - 6
= 6x³ - 33x² + 45x - 6
