Quadratic This words in todays world refers to expressions,equations, that involve sums of constants and first and second powers of variables and no higher powers.
Quadratic expression EQ) ax^2 + bx + c
quadratic equation EQ)ax^2 +bx + c=0 in the variable x and f:x yields ax + bx + c
Binomial square theorem for all real numbers x and y, (x+y)^2=x^2 +2xy +y^2 and (x-y)^2=x^2-2xy+y^2
Absolute value The absolute value of a number can be defiened piecewise as lxl=x,fpr x>0 lxl=-x for x<0
Acceleration due to gravity EQ)h=1/2gt^2 + v0t + h0. velocity is the rate of change of position with respect of time.
Perfect square trinomial EQ)x +h)^2=x^2 + 2hx + h^2.It is called this because it is the square of a binomial.
Quadratic formula theorem if ax^2 + bx + c =0 and a is not equal to 0 then x = -b + or - the square root -4ac all over 2a. Think of song!
Complex number When a real number and an imaginary number are added, the sum is the complex number. EQ) a+bi EX) -3 +4Iis a complex number
