x²+9x-5 find the factor
Answers
Answer:
The first term is, x2 its coefficient is 1 .
The middle term is, -9x its coefficient is -9 .
The last term, "the constant", is -5
Step-1 : Multiply the coefficient of the first term by the constant 1 • -5 = -5
Step-2 : Find two factors of -5 whose sum equals the coefficient of the middle term, which is -9 .
-5 + 1 = -4
-1 + 5 = 4
Observation : No two such factors can be found !!
Answer:
x2 - 9x - 5 = 0
Step-by-step explanation:
1.1 Factoring x2-9x-5
The first term is, x2 its coefficient is 1 .
The middle term is, -9x its coefficient is -9 .
The last term, "the constant", is -5
Step-1 : Multiply the coefficient of the first term by the constant 1 • -5 = -5
Step-2 : Find two factors of -5 whose sum equals the coefficient of the middle term, which is -9 .
-5 + 1 = -4
-1 + 5 = 4
Observation : No two such factors can be found !!
