Question

if one root of the quadratic equation 3 X square + p X - 4 = 0 is 4 find the value of p​

Answer 1

Step-by-step explanation:

if one root of the quadratic equation 3 X square + p X - 4 = 0 is 4 find the value of p

Answer 2

Step-by-step explanation:

if one root of the quadratic equation

3 X ^2+ p X - 4 = 0 is 4

it means X = 4

put the value of of X in whole equation

3(4)^2+p×4 -4 =0

3×16 + 4p -4 = 0

48 -4+4p = 0

44+4p = 0

4p = -44

p = -44/4

p= -11
