X= 67 because you use the basic square train angle method you can find the correct answer.
The standard form of a quadratic equation is: ax²+bx+c=0, and it is represented with a polynomial of degree 2, that's why it is also called "Equation of degree 2".
1. So, if 3 and 8 are zeros of the quadratic function, then they are factors of it. Therefore, you have:
(x+3)(x+8)=0
2. When you write it in the standard form, you have:
x²+11x+24=0
a=1
b=11
c=24
10 * 100 = 1000 so... 10^3 would equal 1000 too
