Answer: x = 41.22 and 38.78
Step-by-step explanation:
Given the equation
4x² - 40x + 94 = 0
Using the general formula
x = -b+/-√b²-4ac/2a
Where a = 4, b= -40 c= 94
x = -(-40)+/-√(-40)²-4(4)(94)/2(4)
x = 40+/-√1600-1504/8
x = 40 +/-√96/8
x = 40 +/-9.8/8
x = 40+/-1.22
x= 40+2.22 = 41.22
and x = 40 -1.22
x = 38.78
