Squares and Square Roots The product of a number and itself is the square of the number.Numbers like 4, 25, and 2.25 are called perfect squares because they are squares of rational numbers.The factors multiplied to form perfect squares are called square roots.Both 5 ? 5 and (25)(25) equal 25.So, 25 has two square

4.3 Least Squares Approximations

4.3 Least Squares Approximations It often happens that Ax Db has no solution. The usual reason is: too many equations. The matrix has more rows than columns. There are more equations than unknowns (m is greater than n). The n columns span a small part of m-dimensional space. Unless all measurements are perfect, b is outside that column space.

To use this factoring technique, we must be able to recognize perfect squares. In section 3—2, we saw that the product of (a + b)(a — b) was a 2 — b2. We refer to the indicated product (a + b)(a — b) as the product of the sum and difference of the same two terms. Notice that in one factor we add the terms and
