Question

Розкладіть на множники 1)5a³-20ab 2)7x³+14x⁵-7x² 3)3a-3b+ax-bx

Answer 1

1)5a(a²-4b)

2)7x²(x+2x³-1)

3)(3+x) (a-b)

Answer 2

1. 5a³ - 20ab:

We can factor out the greatest common factor (GCF) from the expression, which in this case is 5a:

5a(a² - 4b)

The expression is now factored into the product of 5a and (a² - 4b).

2. 7x³ + 14x⁵ - 7x²:

In this expression, we can also factor out the GCF, which is 7x²:

7x²(x + 2x³ - 1)

The expression is now factored into the product of 7x² and (x + 2x³ - 1).

3. 3a - 3b + ax - bx:

We can group the terms together and factor out the common factors:

(a - b)(3 + x)

The expression is now factored into the product of (a - b) and (3 + x).
