Question

Решить (x-1)*(5x+8)....

Answer 1

5х²+8х-5х-8=5х²+3х=х(5х+3)

Answer 2

5x^2+8x-5x-8 вроде всё єто же изи

Answer 3

To solve the expression (x-1)*(5x+8), you can use the distributive property of multiplication to expand the product. After expanding, you can simplify the expression by combining like terms. Here's how you can do it step by step:

Step 1: Use the distributive property to expand the expression. (x-1)*(5x+8) = x * 5x + x * 8 - 1 * 5x - 1 * 8

Step 2: Simplify each term. = 5x^2 + 8x - 5x - 8

Step 3: Combine like terms. = 5x^2 + (8x - 5x) - 8 = 5x^2 + 3x - 8

So, the expanded and simplified expression is 5x^2 + 3x - 8.
