2x^2+8x-7 solve the equation

x = (-4 + √30) / 2, or x = (-4 – √30) / 2

Explanation:

x = (-b ± √b² – 4ac) / 2a →

y = ax² + bx + c

given

y = 2x² + 8x – 7 →

x = (-(8) ± √(8)² – 4(2)(-7)) / 2(2) →

x = (-8 ± √64 + 56) / 4 →

x = (-8 ± √120) / 4 →

x = (-8 ± 2√30) / 4 →

x = (-4 ± √30) / 2 →

x = (-4 + √30) / 2, or x = (-4 – √30) / 2

i would say b
