Answer:
(x+4) (x+12)
Step-by-step explanation:
x^2 +16x+48
What numbers multiply to 48 and add to 16
4*12 = 48
4+12=16
(x+4) (x+12)
To multiply conjugate pairs, first factor any number inside the radical into prime factors, then multiply the coefficients and the radicands, and last but not least simplify the radicans dividing the exponents by the index -the quotient will be the exponent of the term that will came out of the radical and the remainder will be the exponent of the term that will remain inside the radical-
Add E on AB where ED is perpendicular to AB , since the distance between D and AB is 5 in , so ED is 5 in (because the distance between a point and a line is the length of the perpendicular line drawn from the point to the line)
now we have a right angled triangle AED at E , sin(DAE) = DE/AD = 5/10 =1/2
so angle DAE is 30 degrees and since angle CAB is 60 degrees
therefore AD is angle bisector of angle A
