Answer:

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

Answer:

$9^{-7}, 9^{-2}$

Step-by-step explanation:

$\frac{9^5\times9^{-9}}{9^3}\\\frac{9^{-4}}{9^3}\\ 9^{-7}$

When you multiply like terms, you add their powers. When dividing like terms, you subtract their powers (subtract the power in the denominator from the one in the numerator).

$(9^4)^3\times9^{-14}\\9^{12}\times9^{-14}\\9^{-2}$
