Question

3. Given that one of the root is 3 times the others for the quadratic equation 3x^2-2x+p=0, find
a)the value of p
b)the two roots
pls check wether my working and answer is correct @ganeshie8

Answer 1

use general formula of quadratic equation ?

Answer 2

\[\frac{ 2 }{ 3 }\div \frac{ 4 }{ 3 }=\frac{ 1 }{ 2 }\]

Answer 3

Using the quadratic equation will give you 2 equation (using the +/-) each linear eqations in p

solution 1 = 3xsolution 2

so write that equation which will be a simple equation in p

solve for p

then solve the 2 roots from the original quadratic formula
