A new algorithm for generating Pythagorean triples.
... = 2Tn 2 − Un 2 . Thus, provided 2T1 2 − U1 2 = 1, the pairs Un , Tn are solutions of 2T 2 − U 2 = 1, whether or not U1 , T1 are integers. Substituting for T and U with T = Z/a and U = (2X + a)/a in equations 3 and 4 (bearing in mind that the full set of Pythagorean triple solutions is given only for ...

... 3. If it isn’t, look to see what you could multiply by to eliminate a variable. 4. Rewrite the equation you need to multiply and multiply the whole equation by that number. 5. Rewrite the other equation under it. 6. Add the “columns.” 7. Solve for that variable. 8. Substitute that answer into one of ...

Lesson 1 Reteach: Constant Rate of Change
... Step 1 Find the x-intercept. To find the x-intercept, let y = 0. 3x + 2y = 6 Write the equation. 3x + 2(0) = 6 Replace y with 0. 3x + 0 = 6 Multiply. 3x = 6 Simplify. x=2 Divide each side by 3. The x-intercept is 2. Step 2 Find the y-intercept. To find the y-intercept, let x = 0. 3x + 2y = 6 Write t ...
