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
