X cannot equal +2, and can't be -1. If you factor it, then you notice you get 2(x+2)(x-2). If you use either one for the x, one will be zero and the won't, and vise-versa.
Standard form is ax^2+bx+c=0
First evaluate the exponent and expand (foil).
y= 3(x^2-4x+4)+1
Then distribute the 3
y= 3x^2-12x+12+1
Combine like terms
y=3x^2-12x+13
Final answer: 3x^2-12x+13=0
Answer:
PA = XA
Step-by-step explanation:
Construction of an angle bisector,
1). Mark an arc from point W with the help of a compass which intersect lines WS and WZ at the points P and X respectively.
2). Marc two arcs of the same length form the points P and X which intersect each other at a point A.
3). Joint the points A and W.
Thus AW will be the angle bisector of angle PWX where PA = XA.
Therefore, distances PA and XA will be equal in measure.
