Step-by-step explanation:
This should be the correct answer.
The discriminant is the part under the sqrt in the quadratic formula
for ax²+bx+c, the discriminant is b²-4ac
if the discriminant is
less than 0, then there are non-real roots
equal to 0, then there is a double root
greater than 0, then there are 2 real roots (may be rational or irrational)
so
1x²-5x+7
b²-4ac=(-5)²-4(1)(7)=25-28=-3
less than 0 so it is non real roots
answer is D
When you multiply or divide a whole number by a power of ten just add the zeros. 5 to the 100000 power is 500000. Five zeros. Hope this helps. Just a little trick and pattern I noticed which helps. :)
