Question

(x^3-2x^2+5x-7) x (2x). ^2-3x+4​

Answer 1

Step-by-step explanation:

STEP

1

:

Equation at the end of step 1

((2x2 + 3x) - 4) - (x2 - 5x + 7)

STEP

2

:

Trying to factor by splitting the middle term

2.1 Factoring x2+8x-11

The first term is, x2 its coefficient is 1 .

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

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

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

Step-2 : Find two factors of -11 whose sum equals the coefficient of the middle term, which is 8 .

-11 + 1 = -10

-1 + 11 = 10

Observation : No two such factors can be found !!

Conclusion : Trinomial can not be factored

Final result :

x2 + 8x - 11

Answer 2
