Answer: x=(10-sqrt(128))/14=(5-4sqrt(2))/7=-0.094

Step-by-step explanation: (7x2 - 10x) - 1 = 0

STEP

:

Trying to factor by splitting the middle term

2.1 Factoring 7x2-10x-1

The first term is, 7x2 its coefficient is 7 .

The middle term is, -10x its coefficient is -10 .

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

Step-1 : Multiply the coefficient of the first term by the constant 7 • -1 = -7

Step-2 : Find two factors of -7 whose sum equals the coefficient of the middle term, which is -10 .

-7 + 1 = -6

-1 + 7 = 6
