Question

Q. 2 The value of p for equation 2x² – 4x + p = 0 to have real roots will be

(a) p ≤ –2

(b) p ≥ 2

(c) p ≤ 2

(d) p ≥ –2​

Answer 1

Answer:

your answer is here

Step-by-step explanation:

option c is right

Answer 2

If a Quardratic roots have real and equal roots then

${b}^{2} - 4ac = 0$

Here ,

a = 2 , b = -4 , c = p

${ - 4}^{2} - 4(2)(p) = 0 \\ 16 - 8p = 0 \\ \implies - 8p = - 16 \\ \implies \: p = 2$

so option c is correct
