Question

solve the quadratic equation for x and give your answer correct to two decimal place 4x²-5x-3=0​

Answer 1

Step-by-step explanation:

4x² - 5x - 3 = 0

x = -b ±√b² - 4ac ÷ 2a

x = 5 ± √25 + 48 ÷ 8

x = 5 ± √73 ÷ 8

x = 5 + 8.54400375 ÷ 8 or. x = 5 - 8.54400375 ÷ 8

x = 1.69300048. or x = -0.443000469
