Answer:
x = (5 + √73) / 4 or (5 - √73) / 4
Step-by-step explanation:
2x² - 5x - 6 = 0
x = [5 ± √(25 - 4(2)(-6)] / 2(2)
x = [5 ± √(25 + 48)] / 4
x = [5 ± √(73)] / 4
x = (5 + √73) / 4 or (5 - √73) / 4)
y=42
7y = 6×49
y = (6×49)÷7
y= 42
3/5
Set it equal to 0
5x-3=0
Then solve for x
5x=3
x=3/5
Check
5(3/5) - 3
3-3
0
