Final answer:
To simplify the expression -19x² + 14x + 14 using the quadratic formula, we need to first identify the values of a, b, and c. Plugging these values into the quadratic formula gives the simplified expression x = (-14 - √1260) / (-38). So, none of the given options are correct.
Step-by-step explanation:
To simplify the expression -19x² + 14x + 14 using the quadratic formula, we need to first identify the values of a, b, and c in the equation ax² + bx + c = 0. In this case, a = -19, b = 14, and c = 14.
Plugging these values into the quadratic formula, which is x = (-b ± √(b² - 4ac)) / (2a), we get:
x = (-14 ± √(14² - 4(-19)(14))) / (2(-19))
Simplifying further, we have x = (-14 ± √(196 + 1064)) / (-38) = (-14 ± √1260) / (-38).
The simplified expression is therefore x = (-14 + √1260) / (-38) and x = (-14 - √1260) / (-38).
None of the given options are correct.
