Question

$which \: value \: of \: \: m \: \: that \: \: {x}^{2} - 12x + m = 0 \: eqution \: will \: be \: real \: and \: equal$
will be realistic and equal??
​

Answer 1

✒ x² - 12x + m = 0

Let,

• a = 1
• b = - 12
• c = 1

Discrimination (∆) = b² - 4ac = 0

➡ (-12)² - 4(1)(m) = 0

➡ 144 - 4m = 0

➡ 144 = 4m

➡ m = 144/4

➡ m = 36

∴ The value of m is “ 36 ”
