Question

Help lol i need gthe answer to this everytime i do it i get it wrong

Answer 1

Answer:

B

Step-by-step explanation:

You need the equation to equal 0

4x²-5=3x+4 Subtract 4 and 3x from both sides

4x²-5-4-3x

4x²-3x-9

a=4    b=-3    c=-9

(-b±√(b²-4ac))/2a

(-(-3)±√-3²-4(4)(-9))   /   (2(4)
