Answer:
standard form
1.) x² - 14 = 5x
x² - 14 - 5x = 5x - 5x
x² - 5x - 14 = 0
a = 1
b = 5
c = 14
2.) 3x =✓10x² - 5x - 24
3x = 10x² - 5x - 24
3x - 10x² + 5x + 24 = 0
-10x² + 8x + 24 = 0
a= 10
b = 8
c = 24
3.) x² + ( 19 - x)² = 193
x² + (19 - x ) (19 - x ) = 193
x² + 361 - 19x - 19x - x² = 193
2x² + 361 - 38x = 193
2x² + 361 - 193 - 38x = 0
2x² + 168 - 38x = 0
2x² - 38x + 168 = 0
a= 2
b = - 38
c = 168
Step-by-step explanation:
hope its help,
