Question

5x×5x+8x-1 factorize
​

Answer 1

STEP 1:

Equation at the end of step 1

[(0 - 5x2) - 8x] - 1

STEP 2:

STEP

3

:

Pulling out like terms

3.1 Pull out like factors :

-5x2 - 8x - 1 = -1 • (5x2 + 8x + 1)

Trying to factor by splitting the middle term

3.2 Factoring 5x2 + 8x + 1

The first term is, 5x2 its coefficient is 5 .

The middle term is, +8x its coefficient is 8 .

The last term, "the constant", is +1

Step-1 : Multiply the coefficient of the first term by the constant 5 • 1 = 5

Step-2 : Find two factors of 5 whose sum equals the coefficient of the middle term, which is 8 .

-5 + -1 = -6

-1 + -5 = -6

1 + 5 = 6

5 + 1 = 6

Observation : No two such factors can be found !!

Conclusion : Trinomial can not be factored

Final result :

-5x2 - 8x - 1
