Answer:
(x+39) and(x-7) are factors i.e. x= -39 or 7
Step-by-step explanation:
x² + 32x -273 = 0
x² + 32x +(b/2a)² = 273 +(b/2a)²
here b=32 and a= 1
x² +32x + (32/2)² = 273 +(32/2)²
x² + 32x +(16)² = 273+ (16)²
(x + 16)² = 273 + 256
(x+16)² = 529
x+16 = ±√529
x +16 = ±23
x = 23-16=7 and
x= -23-16 = -39
