This can be easily answered using the well-known formulae for solving quadratic equations:
y = 3x2 - 5x + 1
then
x = (5 +- sqrt(25 - 4*3*1))/6
since 25-4*3*1 = 25-12 = 13, which is > 0, this parabola has two intersections with the x-axis (as the quadratic equation has two real roots).

Yes, it crosses at (0.23,0) and (1.43,0).

you have to find the key with the plus and equals symbol. Then push the shift key and the plus/equals key. The "cross" should show up. Plus (+) equals (=). The plus should be above the equals.

Yes, it crosses at (0.23,0) and (1.43,0).
4+1=5. Plus 4 equals 9. Plus 77685769844446473 equals 77685769844446482. Plus 3 equals 77685769844446485. Plus 8 equals 77685769844446493. Plus 1 equals 77685769844446494. Plus 9870998342523322424 equals 1064785604097768918. Plus 4 equals 1064785604097768922.
It is the property that equals plus equals are equals.
the answer is a
No.
If I am correct, 9 plus 7 equals 112.
