THe zero product property you take an equation that is product of the multiplication of two binomials and by factorizing it you take both factors and equalize it to 0 in order to find the value of both values for x.
The quadratic formula is a formula used to solve quadratic equations that can´t be determined by the square root property or the zero product. You just use the numerical terms of the the formula:
And the formula is:
x=
And you just put the values of the quadratic function into the formula.
(x + 3) (x + 2) = 0 To solve it, the most appropriate technique is: 1.) zero product property The solutions are: (x + 3) = 0 x = -3 (x + 2) = 0 x = -2
x² + 6 = 31 To solve it, the most appropriate technique is: 2.) square root property x² = 31-6 x² = 25 x = +/- root (25) x = +/- 5 The solutions are: x = 5 x = -5
Since the score is the sum of all cards a player has, the way to make it smallest is to use the smallest cards. So the 7 smallest cards are 1, 2, 3, 4, 5, 6 and 7. So you want to add these up. This gets 28
