What is the product? (5r - 4)(r² - 6r + 4)

Solution:

Given expression is:

(5r - 4)(r² - 6r + 4)

To find the product,

= 5r(r² - 6r + 4) - 4(r² - 6r + 4)

= 5r³ - 30r² +20r - 4r² +24r -16

Therefore, the product is 5r³ - 34r²+ 44r - 16

What is the product? (5r - 4)(r² - 6r + 4)

Summary:

The product of (5r - 4)(r² - 6r + 4) is 5r³ - 34r²+ 44r - 16
