Description
"Quadratic Radicals" Real Numbers PPT Courseware 4
learning target
1. The quadratic radical will be converted into a quadratic radical with the same radicand.
2. Understand and master simple addition and subtraction of quadratic radicals.
Review the past and learn the new
1. What requirements do the results of quadratic radical calculation and simplification meet?
(1) The radicand number does not contain a denominator; the denominator does not contain a radical.
(2) The radicand number does not contain factors or factors that can solve all squares.
in conclusion:
Similar to merging similar terms, adding and subtracting the coefficients of quadratic radicals with the same radicand, the resulting coefficient, the root sign and the internal root sign remain unchanged.
Steps for addition and subtraction of quadratic radicals:
(1) Convert each quadratic radical into its simplest quadratic radical.
(2) Find the quadratic radicals whose radicands are the same.
(3) Combine quadratic radicals with the same radicand.
Through the study of this class, we need to master:
1. Steps of addition and subtraction of quadratic radicals.
2. Be able to perform operations on quadratic radicals with the same radicand.
