Question

(iv) 2x + 15x + 7 x 1, 4x - x + 9x² + 2x + 11
​

Answer 1

step by step explain:

Factoring 9x2+116x+11

The first term is, 9x2 its coefficient is 9 .

The middle term is, +116x its coefficient is 116 .

The last term, "the constant", is +11

Step-1 : Multiply the coefficient of the first term by the constant 9 • 11 = 99

Step-2 : Find two factors of 99 whose sum equals the coefficient of the middle term, which is 116 .

-99 + -1 = -100

-33 + -3 = -36

-11 + -9 = -20

-9 + -11 = -20

-3 + -33 = -36

-1 + -99 = -100

1 + 99 = 100

3 + 33 = 36

9 + 11 = 20

11 + 9 = 20

33 + 3 = 36

99 + 1 = 100

Observation : No two such factors can be found !!

Conclusion : Trinomial can not be factored

final answer:9x2 + 116x + 11
