Question

What is the solution of x²+3x+1=0

Answer 1

Answer:

Let equation is

ax² + bx + c = 0

Now, according the formula of find factors of x is

x = [(-b) ± √ {(b)² - 4ac}]/2a

Now, given equation is that

x² - 3x + 1 = 0

Here,

a = 1, b = -3, c = 1.

Put these values in the formula

x = [-(-3) ± √{9 - 4×1×1}]/2×1

x = [ 3 ±√5 ] / 2
