Answer:
- y = 4
- y = -3/2 = -1.5
Explanation:
According to quadratic formula:
y = - b ± √ b²- 4ac / 2a
y = - (-5) ± √ -5²- 4(2x-12) / 2(2)
y = 5 ± √ 25 - 4(-24) / 4
y = 5 ± √ 25 - (-96) / 4
y = 5 ± √ 121 / 4
y = 5 ± √ (11)² / 4
y = 5 ± 11 / 4
Now either,
y = 5 + 11 / 4
y = 4
Or,
y = 5 - 11 / 4
y = -3/2 = -1.5
