Question

middle terms splitting x^2-3x+1​

Answer 1

Step-by-step explanation:

$\bf{Here \: we \: go!!}$

• Steps for doing this sum,

=>Pulling out like terms.

=>Trying to factor by splitting the middle term.

$\huge\tt\fbox\purple{Answer}$

=> x2 - 3x + 1 = 1 (x2 - 3x + 1)

=>The first term is, x2 its coefficient is 1 .

=>The middle term is, -3x its coefficient is -3 .

=>The last term, "the constant", is +1.

=>Multiply the coefficient of the first term by the constant   1 • 1 = 1 

=>Find two factors of 1 whose sum equals the coefficient of the middle term, which is -3 .

That's it we have arrived with our answer,

$\bf{x = \dfrac{ - 3 - \sqrt{5} }{ - 2} = > 2.618}$

$\bf{x = \dfrac{ - 3 + \sqrt{5} }{ - 2} = > 0.382}$
