The discriminant is b^2-4ac
ax^2+bx+c=0
x^2+11x-10=0
11^2-4(1)(-10)
1. Simplify 11^2 to 121
121-4(1)(-10)
2. Simplify 4*1*-10 to -40
121-(-40)
3. Simplify brackets
121+40
4. Simplify
161
Your discriminant is 161
Multiplying exponents will just have to follow a rule.
Make sure that the base are the same otherwise, you keep it as is.
If they have the same bases, then just add the exponents.
= (5a^5)(6a^6)
= 30a^11
So the final answer is <span>30a^11.</span>
Answer:
50 is the answer because you can divide 2 numbers to get this number.
Answer:
4-7
this gives us answer of -4
hope it helps
Given two points (x₁,y₁) and (x₂,y₂) the midpoint would be:
M=((x₁+x₂)/2 , (y₁+y₂)/2)
In this case, the points would be: (1,2) and (1,-5); therefore:
M=((1+1)/2 , (2-5)/2)=(2/2,-3/2)=(1, -3/2)
<span>Answer: B) (1,-3/2)</span>
