Question

(I) Solve the equation. x2 + -5x + 6=0

Answer 1

Step-by-step explanation:

x² - 5x + 6 = 0

x² - 2x - 3x + 6 = 0

x (x - 2 ) -3 (x - 2 ) = 0

(x -2) (x - 3) = 0

x- 2 = 0 and x-3 = 0

x = 2 x = 3

Answer 2

Answer:

answer is x = 1 and 6

Step-by-step explanation:

x² + (5x) + 6 = 0

x² + 5x + 6 = 0

x² + (6 -1)x + 6 = 0

x² + 6x - x + 6 = 0

x(x - 6).-1(x - 6) = 0

(x - 1) (x - 6) = 0

x - 1 = 0 , x - 6 = 0

x = 1 , x = 6
