Answer:
This is the case ASA, with 2 triangles are congruent (ABD and CBE)
ABD = CBE because
Angle BAD = Angle BCE (as pic)
AD = CE (as pic)
Angle ADB = Angle CEB
Step-by-step explanation:
Angle ADB = Angle CEB because
ADB = 180 - BAD - B
CEB = 180 - BCE - B
BAD = BCE (as pic)

f(X)= 3x^2- 30x+5
f(X)= 3(x-5)^2-70
= 3(x^2-2.x.5+ 5^2) -70
= 3(x^2-10x+25)-70
= 3x^2-30x+75-70
= 3x^2-30x+5
