what does it mean when 2 lines intersect on a graph?
the system has one solution
simplify x5 times x3
x8
classify the polynomial and state the degree
2x2y + 7y2
binomial and 3
whats the greatest common factor
6x3 + 3x2
3x2
solve by factoring
x2 + 2x - 15 = 0
x = -5, 3
when lines on graphs are parallel, what does it mean about their slope and solution
same slope, no solution
simplify x7 divided by x3
x4
(2x3 + 3x + 3) + (4x3 + 2x2 - x - 5)
6x3 + 2x2 + 2x - 2
Factor
4x2 + 2x
2x(2x + 1)
what is the quadratic formula
see board
what do you need to do first to eliminate y in this system
3x + 2y = 8
x - 4y = 3
multiply top equation by 2
write 2576000 in scientific notation
2.576 x 106
(4x2 - x + 2) - (x2 + 3x - 5)
3x2 - 4x + 7
factor
x2 + 7x + 12
(x + 3) (x + 4)
what is the vertex
(x - 2)2 + 6
(2, 6)
solve by substitution
y = 2x + 3
3x + y = 9
x = 6/5, y = 27/5
(x3y2z)4
x12y8z4
(x - 3)(x2 + 4x - 1)
x3 + x2 - 13x + 3
Factor
x2 - 49
(x + 7)(x -7)
solve by quadratic formula
x2 - 6x + 8 = 0
x = 2, 4
solve by elimination
2x + 3y = 12
4x - 3y = 6
x = 3, y = 2
(a3b2)2 / a2b
a4b3
(15x4 - 10x3 + 5x2) / 5x2
3x2 - 2x + 1
factor
3x2 + 14x + 8
(3x + 4) (x + 2)
what is the vertex, line of symmetry and how does it open
-4(x + 9)2 - 3
(-9, -3)
x = -9
