Linear Regression: What is the Sum of Squares?
WebWe had: 36a^8 + 2a^6. To write a number as a square, we just use the square root of that number and put all squared (as the square root will cancel out the square). So X = (√X)^2. For example, 9 = (√9)^2 = 3^2. Then, to write 2a^6 as a square, we may do ( √ [2a^6] )^2 = (√2 * a^3)^2. Now we have.
