Answer:
Step-by-step explanation:
X²=12x-40
X²-12x+40=0
a=1 and b= -12 and c = 40
delta = b² - 4ac
delta = (-12)² - 4(1)(40) = 144 - 160 = - 16 = (4i)² ....i² = -1
x1= (12-4i)/2 =6-2i
x1= (12+4i)/2 =6+2i
Answer:
It does = 20 you're correct :)
Step-by-step explanation:
The values of a and b from the equation is -10 and 32
Given the equation expressed as 
Expand the right side of the equation to have:

Simplify the result to have:

Compare both sides of the equation:
ax = -10x
a = -10
Similarly;
b = 32
Hence the values of a and b from the equation is -10 and 32
