30 find all the solutions to the quadratic equation y = 2x(x – 3) = - 5

x = ± i

rearrange the equation and equate to zero

2x² - 6x = - 5 ⇒ 2x² - 6x + 5 = 0

this doesn't factor with integers, hence use the quadratic formula to solve

with a = 2, b = - 6 and c = 5

x = (6 ± √(36 - 40 ) )/4

  = (6 ± √(-4) ) / 4

  = (6 ± 2i ) / 4

x = ± i

a

step-by-step explanation:

i need the pts ignore this answer

a = 11 : 4

b = 38

c = 1 for every 6
