:

Equation at the end of step 1

((0 - 23x2) + 9x) - 3 = 0

STEP

3

:

Pulling out like terms

3.1 Pull out like factors :

-8x2 + 9x - 3 = -1 • (8x2 - 9x + 3)

Trying to factor by splitting the middle term

3.2 Factoring 8x2 - 9x + 3

The first term is, 8x2 its coefficient is 8 .

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

The last term, "the constant", is +3

Step-1 : Multiply the coefficient of the first term by the constant 8 • 3 = 24

Step-2 : Find two factors of 24 whose sum equals the coefficient of the middle term, which is -9 .

-24 + -1 = -25

-12 + -2 = -14

-8 + -3 = -11

-6 + -4 = -10

-4 + -6 = -10

-3 + -8 = -11

-2 + -12 = -14

-1 + -24 = -25

1 + 24 = 25

2 + 12 = 14

3 + 8 = 11

4 + 6 = 10

6 + 4 = 10

8 + 3 = 11

12 + 2 = 14

24 + 1 = 25

Observation : No two such factors can be found !!

Conclusion : Trinomial can not be factored

Equation at the end of step

:

-8x2 + 9x - 3 = 0

Answer 2

Answer:

9x=3+2and8x+2x=2

9x=5 and 10x=2

x=9/5 and x=10/2

x=9/5andx=5

this is yours answer

l hope you helpful.
