Answer:
for ax^2 + bx +c
a)You have to find 2 numbers with the product of c and the sum of b
(x-1)(x-1)
b) here you should use quadratic formula
[tex]\frac{-b+-\sqrt{b^{2} - 4ac} }{2a} = \frac{-(-3)+-\sqrt{(-3)^{2} - 4(1)(1)} }{2(1)} = \frac{3+-\sqrt{5} }{2}[/tex]
so it will be
[tex](x+ \frac{3-\sqrt{5} }{2})( x - \frac{3+\sqrt{5} }{2})[/tex]
