Math Problem Statement

(5x - 3)(x - 2)

Solution

To expand the expression (5x3)(x2)(5x - 3)(x - 2), we use the distributive property (also known as the FOIL method for binomials):

  1. First: Multiply the first terms in each binomial: 5xx=5x25x \cdot x = 5x^2
  2. Outer: Multiply the outer terms: 5x(2)=10x5x \cdot (-2) = -10x
  3. Inner: Multiply the inner terms: 3x=3x-3 \cdot x = -3x
  4. Last: Multiply the last terms: 3(2)=6-3 \cdot (-2) = 6

Now, add all these results together:

5x210x3x+65x^2 - 10x - 3x + 6

Combine the like terms 10x-10x and 3x-3x:

5x213x+65x^2 - 13x + 6

So, the expanded form of (5x3)(x2)(5x - 3)(x - 2) is:

5x213x+65x^2 - 13x + 6
