7/15 will be the most you can simplify
Answer:
Step-by-step explanation:
Rewrite this quadratic in standard form: 3x^2 + 7x - 1.
The coefficients of x are {3, 7, -1}, and so the discriminant is b^2 - 4ac, or
7^2 - 4(3)(-1), or 49 + 12, or 61. Because the discriminant is positive, this quadratic has two real, unequal roots
-6,-2,-1,3,4 that's it then you're done
he bought 34 pencils which I suppose aren't already sharpened
so if he sharpens 16 of them just subtract 16 from 34 (34-16) which equals 18
so the ratio would be 16:18
but if u need to simplify it would be 8:9
