DUE IN 10 MIN PLEASE HELP use the method of completing the square to find the x-intercepts. (Use the Equation Editor to show all steps) y=x^2 - 14x + 48

Step-by-step explanation:

complete the square:

Take a quadratic equation : ax²+bx+c and turn it to

a(x+d)²+e

d=b/2a and e=c-b²/4a

y=x^2 - 14x + 48

a=1 , b=-14 , c=48

d=-14/2=-7

e= 48-14²/4

e= 48-49

e=-1

complete the square  for y=x²-14x+48

y= (x-7)²-1

point a is the center of this circle.

the ratio of the lengths of (ef/bc) and (ad/ih) is 2: 1.

step-by-step explanation:

< coa = 150 ( given)

as ba and bc are tangents

so oc and oa is perpendicular to cb and ab respectively because in circle normal passes through centre

so in quadrilateral oabc

< coa + < oab + < ocb + < abc = 360

150 +90+90 + < abc = 360

330 + < abc = 360

< abc = 360 -330 = 30

so < abc = 30
