Question

simplify
$10x ^{2} + 9x - 10$
​

Answer 1

Step-by-step explanation:

STEP

1

:

Equation at the end of step 1

((2•5x2) + 9x) - 10

STEP

2

:

Trying to factor by splitting the middle term

2.1 Factoring 10x2+9x-10

The first term is, 10x2 its coefficient is 10 .

The middle term is, +9x its coefficient is 9 .

The last term, "the constant", is -10

Step-1 : Multiply the coefficient of the first term by the constant 10 • -10 = -100

Step-2 : Find two factors of -100 whose sum equals the coefficient of the middle term, which is 9 .

-100 + 1 = -99

-50 + 2 = -48

-25 + 4 = -21

-20 + 5 = -15

-10 + 10 = 0

-5 + 20 = 15

-4 + 25 = 21

-2 + 50 = 48

-1 + 100 = 99

Observation : No two such factors can be found !!

Conclusion : Trinomial can not be factored

Final result :

10x2 + 9x - 10
