Answer:
X^2 -2x-35 =0
Step-by-step explanation:
For equation with solution X= -5 and 7
It implies
X+5 =0 or X-7=0
(X+5)(X-7)=0
x2 -7x + 5x -35=0
X^2-2x-35=0
Answer:
2 and 6
Step-by-step explanation:
First factor x from the expression
x^2-2x-6x+12=0
x(x-2)-6x + 12=0
Then factor out x-2 from the expression
x(x-2)-6x + 12=0
(x-2)(x-6)=0
When the product of factors equals 0, at least one factor is 0
(x-2)(x-6)=0
x-2=0
x-6-0
And so
X=2
X=6
Answer:
Let m = Number of months
Company A: 60+ 42.95 m
Company B: 25+49.95 m
60+ 42.95 m= 25+49.95 m
Subtract 42.95 from both sides
60 = 25 + 7m
Subtract 25 from both sides
35= 7m
Divide both sides by 7
<u>m = 5</u>

For this case we have:
Polynomial 1: P (x) = 9-3x ^ 2
Polynomial 2: Q (x) = - 8x ^ 2 + 4x + 5
Sorting the polynomials:
Polynomial 1: P (x) = - 3x ^ 2 + 9
Polynomial 2: Q (x) = - 8x ^ 2 + 4x + 5
Adding term to term (similar) we have:
P (x) + Q (x) = (- 3-8) x ^ 2 + (0 + 4) x + (9 + 5)\\P (x) + Q (x) = - 11x ^ 2 + 4x + 14
Answer:
A (x) = P (x) + Q (x) = - 11x ^ 2 + 4x + 14
