Answer 1

Answer:

answer for the given problema is ±12

Answer 2

$\huge\underline\mathbb{\red S\pink{O}\purple{L} \blue{UT} \orange{I}\green{ON :}}$

★ Given that,

Find the value of k so that the two roots of the equation x² - kx + 36 = 0 are equal.

★ Let,

• a = 1
• b = - k
• c = 36

By using discrimination (∆) formula...

↪ b² - 4ac = 0

➡ (-k)² - 4(1)(36) = 0

➡ k² - 144 = 0

➡ k² = 0 + 144

➡ k² = 144

➡ k = √144

➡ k = 12

Hence, the Value of k is " 12 " .
