Description
"Method of Raising Common Factors" PPT
Part One: Knowledge Review
Factoring:
1.a2-12ab+36b2
2.9x2y2+6xy+1
3.a2b2-4c2
4.x4-2x2y2+y4
Can the polynomial ab+ac+ad be converted into product form?
Because a(b+c+d)=ab+ac+ad
So ab+ac+ad=a(b+c+d)
a is a factor that all terms ab�ac�ad in the polynomial ab+ac+ad have, and is called the common factor of each term of the polynomial.
PPT on common factor method, part 2: discussion
Do the terms of the following polynomials have common factors?
If so, what is it?
(1)a2b+ab2
(2)3x2-6x3
(3)9abc-6a2b2
Find the common factors of the following formulas and fill them in on the horizontal lines.
(1)ab,2a2b,3ab2______.
(2)6mn2,-18m2n2,24m3n____.
(3)7x2y,14xy2z,-35xyz2_____.
The common factor coefficient should be the greatest common divisor of the coefficients, the letters should be the same letters for each term, and the exponent of each letter should be the smallest.
Common factor method PPT, the third part: practice
1. If n is a natural number, is n2+n an odd number or an even number?
Cut two circles with diameters a and b from a circular steel plate with diameter (a+b), and find the area of the remaining steel plate.
Summary
1. If there is a common factor, you must first mention the common factor.
2. It must be decomposed until each polynomial factor cannot be decomposed.
