Cards in this deck (7)
- 1Polynom\[a+bx+cx^2+dx^3+...\]
Ex: \(2.15+2.1x-0.41x^2\)
\(-3x+8\) - 2GradtalHögsta exponenten i ett polynom
Grad 2: \(2.15-0.41x^2\)
Grad 1: \(-3x+8\) - 3\(-(2x-3)=\)\(-(2x-3)=-2x+3\)
Parentesregel: \(-(a-b) = -a+b\) - 4\(2x(x^2-5x)=\)\(2x(x^2-5x)=2x^3-10x^2\)
Distributiva lagen: \(a(b+c)=ab+ac\) - 5\((7-2x)(3-4x)=\)\((7-2x)(3-4x)=\\7\cdot3-7\cdot4x-2x\cdot3+2x\cdot4x\)
Distributiva lagen: \((a+b)(c+d)=ac+ad+bc+bd\) - 6\((3x+2)(3x-2)=\)\((3x+2)(3x-2)=9x^2-4\)
Konjugatregeln: \((a+b)(a-b)=a^2-b^2\) - 7\((y-5)^2=\)\((y-5)^2=y^2-10y+25\)
Kvadreringsreglerna:
\((a+b)^2=a^2+2ab+b^2\)
\((a-b)^2=a^2-2ab+b^2\)
