9x^2 - 35x - 8 = 0 using splliting method solve this equation
Answers
Answer:
Trying to factor by splitting the middle term
Step-by-step explanation:
2.1 Factoring 9x2-35x-8
The first term is, 9x2 its coefficient is 9 .
The middle term is, -35x its coefficient is -35 .
The last term, "the constant", is -8
Step-1 : Multiply the coefficient of the first term by the constant 9 • -8 = -72
Step-2 : Find two factors of -72 whose sum equals the coefficient of the middle term, which is -35 .
-72 + 1 = -71
-36 + 2 = -34
-24 + 3 = -21
-18 + 4 = -14
-12 + 6 = -6
-9 + 8 = -1
-8 + 9 = 1
-6 + 12 = 6
-4 + 18 = 14
-3 + 24 = 21
-2 + 36 = 34
-1 + 72 = 71
Observation : No two such factors can be found !!
Conclusion : Trinomial can not be factored
