WebYou may be thinking that if you square the left side that it becomes 2x-7+9. It doesn't. (a+b)^2 never equals a^2+b^2. Here's what happens if you square both sides immediately [sqrt(2x-7)-3]^2 = 4^2 The left side is a binomial squared, so use FOIL or extended distribution to square that side. 2x-7 -3sqrt(2x-7) - 3sqrt(2x-7) + 9 = 16 2x+2-6sqrt ... WebIt is called "Pythagoras' Theorem" and can be written in one short equation: a 2 + b 2 = c 2. Note: c is the longest side of the triangle; a and b are the other two sides; Definition.
