What quadratic has roots of x=8 and x= -5

Mathematics
1 answer:
Alexxx [7]3 years ago
6 0

Answer:

The quadratic is f(x) = x² - 3x - 40

Step-by-step explanation:

If the roots are x=8 and x= -5, the factors are (x - 8) and (x + 5).

The quadratic is then:

f(x) = x² + 5x - 8x - 40, or x² - 3x - 40

The quadratic is f(x) = x² - 3x - 40

iris [78.8K]

complementary angles = 90

2x-5 + 5x+4 = 90

combine like terms

7x-1 =90

7x = 91

divide by 7

x =13

angle a

2x-5
