Question

factories z²-5root 2z +12​

Answer 1

Answer:

z = 3√2               ;                          z = 2√2

Step-by-step explanation:

z² - 5√2z + 12 = 0

Using Splitting the middle term method,

z² - 3√2z - 2√2z + 12 = 0

z(z - 3√2) - 2√2(z - 3√2) = 0

(z - 3√2)(z - 2√2) = 0

z - 3√2 = 0                                   z - 2√2 = 0

z = 3√2                                         z = 2√2
