Answer:
Explanation:
Rewrite this quadratic equation in standard form:
17x² + 7x - 20 + 8 = 0, or 17x² + 7x - 12 = 0.
The coefficients are a = 17, b = 7 and c = -12. The discriminant, b²-4ac, is then 49-4(17)(-12), or 865. Because this discriminant is positive, we have two real, unequal roots. They are:
-7 ± √865 -7 ± √865
x = ------------------- = ---------------------
2(17) 34
