2x^2 +1x - 12 = 0
Steps Using MOE Approved Calculator Casio Fx 95 MS to solve for x
Press ON
Press Mode twice
Press 1 for Eqn
Press right arrow once
Press 2 for degree 2 ie quadratic equation ax^2 + bx + c = 0
Press 2 for a
Press 1 for b
Press -12 for c
Press =
x1 = 2.21,
Press =
x2 = - 2.71
Answer
x = 2.21, - 2.71
Simultaneous Equations
Solve the simultaneous equations
2x - 3y = 15
3x - 7y = 27 1/2
Steps Using MOE Approved Calculator Casio Fx 95 MS to solve for x and y
Press ON
Press Mode twice
Press 1 for Eqn
Press 2 for 2 unknowns ie simultaneous equations
a1 x + b1 y = c1
a2 x + b2 y = c2
Press 2 for a1
Press - 3 for b1
Press 15 for c1
Press 3 for a2
Press - 7 for b2

Press =
x = 4.5,
Press =
y = - 2
Answer
x = 4.5 , y = - 2
I think it is better to work it out as working carries points as well...
Dear caleb_chiang,
The use of the calculator is only used for checking the answers.
Just in case, students make careless mistakes in their answers.
Students still need to show their workings.
