J and K are on plane BFG and J and I are on plane BAD
Answer:
b = 10
b = 17
Step-by-step explanation:
Hello!
Usually, when you want two different integer solutions, you probably want the quadratic to be factorable.
So what we want to know is that b should be the sum of the factors in 16.
Factors of 16: 1, 2, 4, 8, 16
Factor pairs:
Factor Sums:
These are our possible b-values.
Check:
Let's try 17 first:
- x² - 17x + 16 = 0
- (x - 16)(x - 1) = 0
- x = 16, x = 1
Now 10:
- x² - 10x + 16 = 0
- (x - 8)(x - 2) = 0
- x = 8, x = 2
And finally, 8:
- x² - 8x + 16 = 0
- (x - 4)(x - 4) = 0
- x = 4, x = 4
Since x = 4 is a repetitive integer, we cannot use 8 as a value for b.
The answers are b = 10, and b = 17.
Answer:
10x^3 - 34x^2 + 33x - 7
Step-by-step explanation:
Multiply each term of the trinomial by each term of the binomial. Then combine like terms.
(2x^2 - 4x + 1)(5x - 7) =
= 10x^3 - 14x^2 - 20x^2 + 28x + 5x - 7
= 10x^3 - 34x^2 + 33x - 7
