Expanding and Simplifying (6x+1)(1−3x)

This article will guide you through the process of expanding and simplifying the expression (6x+1)(1−3x) into standard form.

Understanding Standard Form

Standard form for a polynomial refers to the arrangement of terms in descending order of their exponents. For example, a quadratic expression in standard form would be ax² + bx + c.

Expanding the Expression

To expand the expression, we will use the FOIL method (First, Outer, Inner, Last).

  1. First: Multiply the first terms of each binomial: (6x)(1) = 6x

  2. Outer: Multiply the outer terms of the binomials: (6x)(-3x) = -18x²

  3. Inner: Multiply the inner terms of the binomials: (1)(1) = 1

  4. Last: Multiply the last terms of each binomial: (1)(-3x) = -3x

Now we have: 6x - 18x² + 1 - 3x

Simplifying the Expression

Combine the like terms:

  • -18x² (highest exponent term)
  • 6x - 3x = 3x
  • 1 (constant term)

Therefore, the simplified expression in standard form is -18x² + 3x + 1.
