x 3 + 6x2 + 11x + 6
x 4 + 2 x 2-3
AB + ac + b2 + 2bc + c2
A3-b3 + c3 + 3abc
Lesson 2: for functions:
search conditions of x to A means.
A shortening.
Computer x to A < 1.
Post 3: prove the inequality:
For a + b + c = 0. Prove that: a3 + b3 + c3 = 3abc.
For a, b, c are the sidelengths of the triangle. Proof that:
Prove that x 5 + y5 ≥ x4y + xy4 with x, y ≠ 0 and x + y ≥ 0
Lesson 4: solve the equation:
x 2-3 x + 2 + | x-1 | = 0
Lesson 5: find the largest and smallest value (if any)
A = x 2-2 x + 5
B =-2 x 2-4 x + 1.
C =
Lesson 6: calculate the value of expression.
Know a – b = 7 feature: A = (a + 1) a2-b2 (b-1) + ab-3ab (a-b + 1)
For three numbers a, b, c is not zero catches up deals for equality:
Computer: P =
Article 7: proof that
8351634 + 8241142 divisible 26.
A = n3 + 6n2-19n-24 divisible by 6.
B = (10n-9n-1) divisible 27 with n in N *.
