Question

Factorize : 2x2− 13x + 18

Answer 1

Step-by-step explanation:

(x-2)(2x-9)

x=2, x=9/2

Answer 2

The first term is, 2x2 its coefficient is 2 .

The middle term is, -13x its coefficient is -13 .

The last term, "the constant", is -18

Step-1 : Multiply the coefficient of the first term by the constant 2 • -18 = -36

Step-2 : Find two factors of -36 whose sum equals the coefficient of the middle term, which is -13 .

36 + 1 = -35

-18 + 2 = -16

-12 + 3 = -9

-9 + 4 = -5

-6 + 6 = 0

-4 + 9 = 5

-3 + 12 = 9

-2 + 18 = 16

-1 + 36 = 35
