Here are the steps require for Squaring Binomials:

Step 1: When squaring a binomial, don’t be lazy and write it twice. Then distribute or use the FOIL method to multiply the two binomials. There are formulas that you can memorize, but I suggest that you just write it twice and distribute or FOIL.
Step 2: Combine like terms.

Example 1 – Multiply: (3x – 7)2

Step 1: Don’t be lazy, write it twice and then distribute or use the FOIL method to multiply the binomials.
Step 1
Step 2: Combine like terms.
Step 2

Example 2 – Multiply: (4x + 5)2

Step 1: Don’t be lazy, write it twice and then distribute or use the FOIL method to multiply the binomials.
Step 1
Step 2: Combine like terms.
