Question

find the product of given question.???

Answer 1

your solution will be
product of (x+3)(x-4)(x-5)
=x(x-4)+3(x-4)(x-5)
=x²-4x+3x-12(x-5)
=(x²-x-12)(x-5)
=x(x²-x-12)-5(x²-x-12)
=x³-x²-12x-5x²+5x+60
=x³-6x²-7x+60 ans.

Answer 2

❖ Solution ❖

Q. (x + 3) (x - 4) (x - 5)

= (x² - 4x + 3x - 12) (x - 5)

= (x² - x - 12) (x - 5)

= (x³ - 5x² - x² + 5x - 12x + 60)

= (x³ - 6x² - 7x + 60)

`
∴ Answer » (x³ - 6x² - 7x + 60)

❖ Explaination ❖

First of all, we will multiply (x + 3) and
(x - 4)

Then, we will multiply the product of
(x + 3) (x - 4) with (x - 5) to get the answer

When multiplying this numbers

(x + 3) (x - 4)

Divide (x + 3) into x & 3

x(x - 4) + 3(x - 4)

= (x² - 4x) + (3x - 12)

= (x² - 4x + 3x - 12)

= (x² - x - 12)

Then go with the second part !
