Question

If one root of the quadratic equation 3x² + px + 4 = 0 is then find the value of p and the other root of the equation
PLEASE HELP ME ​

Answer 1

Answer:

p = 6

Step-by-step explanation:

Compare the equation with ax² + bx + c

a = 3 b=p c= 4

b²- 4ac = (p²) - 4 ×3 × 4

0 = p² - 36

36 = p²

therefore p = 6

Answer 2

안녕하세요 좋은 아침만나서 반가워요

3x2 + px + 4 = 0 3( 2 3 23)2 + p( 2 3 23) + 4 = 0 4 3 43 + 2 p 3 + 4 2p3+4 =0 P = -8 3x2 - 8x + 4 = 0 3x2 - 6x - 2x + 4 = 0 x = 2/3 or x = 2 Hence, x = 2
