Answer:
D
Step-by-step explanation:
Given the root of a quadratic equation x = a then the factor is (x - a)
Here the roots are x = 5 and x = 7 , then the corresponding factors are
(x - 5) , (x - 7)
The equation is then the product of the factors, that is
y = (x - 5)(x - 7) ← expand using FOIL
= x² - 7x - 5x + 35 ← collect like terms
y = x² - 12x + 35 → D
Using distributive property, factor out the coomon term to get the equivalent expression
<em><u>Solution:</u></em>
Let us first understand about distributive property
The distributive property lets you multiply a sum by multiplying each addend separately and then add the products.
The distributive property can be represented as:
a(b + c) = ab + bc
Let us consider a expression
30 + 5x
We have to write a equivalent expression
Use the distributive property
30 = 6 x 5
Thus 30 + 5x becomes,
Factor out 5 from above expression
Thus, equivalent expression is 5(6 + x) for 30 + 5x
Answer:
y = 2x + 7
