Question

6xsquare -5x -21 converted into (a+b) square​

Answer 1

Step-by-step explanation:

The first term is, 6x2 its coefficient is 6 .

The middle term is, -5x its coefficient is -5 .

The last term, "the constant", is -21

Step-1 : Multiply the coefficient of the first term by the constant 6 • -21 = -126

Step-2 : Find two factors of -126 whose sum equals the coefficient of the middle term, which is -5 .

-126 + 1 = -125

-63 + 2 = -61

-42 + 3 = -39

-21 + 6 = -15

-18 + 7 = -11

-14 + 9 = -5 That's it
