Question

i) Solve the quadratic equation by factorization method. x2 - 15x+54=0​

Answer 1

Answer:

x=-9,-6

Step-by-step explanation:

$x {}^{2} - 15x + 54$

Answer 2

Answer:

X² – 15x + 54 = 0

⇒ x² - 9x - 6x + 54 = 0

⇒ x (x - 9) - 6 (x - 9) = 0

⇒ (x - 6) (x - 9) = 0

⇒ (x - 6) = 0 or (x - 9) = 0

⇒ x = 6 or x = 9

So, 6 and 9 are the roots of the given quadratic equation.
