Question

Please i have exam tomorrow and no one to teach Do in ur book and show​

Answer 1

Step-by-step explanation:

Answer of 6

suppose a and b are the roots (zero) of the equation

a + b = -b/a = 0

0 = p + 3 / 2

p + 3 = 0

p = -3

Answer of 7

ab = c/a

Answer of 8

a + b = - b/a

Answer of 9

x² + 9x + 20 = 0

x² + 4x + 5x + 20 = 0

x(x+4) + 5(x+4) = 0

(x+4) (x+5) = 0

x = -4 or x = -5

so the roots of the equation are -4 and -5.

I hope you understand if you not understood then don't worry this topic will be the easiest topic in maths in higher education
