Answer:
(x + 2)(x + 5)
Step-by-step explanation:
For factored form you have to determine what two numbers multiplied by each other equal c that also, when added to each other, equal b.
Y= ax^2 + bx + c
a=1
b=7
c=10
the factors of 10 are 1, 2, 5, 10
and 2 + 5 = 7
and in factored form with a = 1
(x + 5)(x + 7)
5 wholes = 5
2 fifths = 2/5
5 - 2/5 = 4 3/5 (4 and 3 fifths)
Answer = 4 3/5
Check work:
4 3/5 + 2/5 = 5 (wholes)
Just substitute 5 into a and -2 into k
