solving quarter 1 Flashcards
equation
has an equal sign, can solve for a variable
solution
what makes the equation true
inequality
a range of answers that all could make the statement true
linear
a straight line graph that has a constant slope- degree 1
solve for a variable means
get x alone
a number is a solution if
when you plug it back in the equation makes sense
you can only solve for x in a quadratic if it is equal to
0
you solve for a quadratic by
factoring
once a quadratic is factored, how do you get the solutions?
set each set of ( ) equal to zero and solve
< or > signs means the circle on the number line will be
open
< or > signs means the circle on the number line will be
closed
