Quadratics
What are the real roots of:
x^2 + 9x + 18 = 0
x = -6, x = -3
What is the solution to the following equation?
(x - 24)/8 = (2x + 1)/2
x = -4
-3x + 8 > 2x - 2
x < 2
Solve {(y = -3x + 4), (y = 3x - 2)}
(1, 1)
What values of x are solutions of
2x^2- 5x - 3 ?
x = -1/2, x = 3
Solve
11 + 3(x - 2) = 3x - 1
No Solution
x - 3(x + 2) > 4
x<-5
Solve { (4x + y = 2), (x - y = 3)}
(1, -2)
What are the zeroes of the function, f?
f(x) = x^2 - 10x + 21
x = 7, x = 3
Solve this for y.
x = (2y - z)/5
y = (5x + z)/2
4(3a - 6) < 14a - 10
-7 > a or a < -7
Solve {(8x - 2y + 18 = 0), (y = 4x + 9)}
