Write a polynomial of least degree with roots 7 and – 5. Write your answer using the variable x and in standard form with a leading coefficient of 1.

y = x² − 2x − 35

Step-by-step explanation:

y = 1 (x − 7) (x − (-5))

y = (x − 7) (x + 5)

y = x² + 5x − 7x − 35

y = x² − 2x − 35

x = 3 ± √(5+y)

secant-secant formula:

(whole secant) x (external part) =           (whole secant) x (external part)

(8+y-2) *8=                                           (y+4+6) *6

(y+6)*8 = (y+10) *6

distribute

8y+48 = 6y +60

subtract 6y from each side

2y +48 = 60

subtract 48 from each side

2y = 12

divide by 2

y = 6

sv =     (y+4+6)

sv   = 6+4+6

sv = 16
