Answer:
Since both terms are perfect squares, factor using the difference of squares formula.
(x+9y)(x−9y)
If you find the discriminant it will tell you the number and types of roots. The discriminant is the value b^2 -4ac.
a = 1
b = 1
c = 1
1^2 - 4*1*1
1-4 = -3
Since this is a negative number there will be 2 complex roots.
Answer:
(2x - 3) ^2 - 11x - 6
Step-by-step explanation:
Use the formula I = PRT.....you'll get $2000
Answer:
Slope of the perpendicular line: 2/3
Step-by-step explanation:
-2y = 3x - 6
y = - 3/2x - - 6/2
y = -3/2 + 3
