Use the quadratic formula to solve the equation x^2-3x+2=0

Mathematics
1 answer:
Flura [38]4 years ago
3 0

Answer:

x= 1, 2

Step-by-step explanation:

The quadratic formula is x=\frac{-b+/-\sqrt{b^2-4ac} }{2a}. Here a=1, b=-3, and c=2.

Substitute and you'll have:

x=\frac{-b+/-\sqrt{b^2-4ac} }{2a} =\frac{3+/-\sqrt{(-3)^2-4(1)(2)} }{2(1)}=\frac{3+/-\sqrt{9-8} }{2)}

\frac{3+/-\sqrt{1} }{2}=\frac{3+/-\sqrt{1} }{2}=\frac{3+/-1 }{2}= 2 , 1

True or false. the segments below could form a triangle, 9, 4, 11
natita [175]
True. There are two ways to solve this; one, a shortcut , which is when you add each of them up and they are greater than each other (9+4= 13, which is greater than 11), or you could also use the Pythagorean theorem to solve the problem; the formula is
a squared + b squared= c squared
