Answer 1

Answer:

Step-by-step explanation:

O

3x² - 11x - 4 = 0

a = 3 ; b = -11 , c = -4

$Sum \ of \ roots = \dfrac{-b}{a}=\dfrac{-(-11)}{3}=\dfrac{11}{3}\\\\Product \ of \ roots =\dfrac{c}{a}=\dfrac{-4}{3}$

W

8x² + 12x = -1

8x² + 12x + 1 = 0

a = 8 ;  b = 12 ; c = 1

$Sum \ of \ roots =\dfrac{-b}{a}=\dfrac{-12}{8}=\dfrac{-3}{2}\\\\Product \ of \ roots = \dfrac{c}{a}=\dfrac{1}{8}$

L

x² + x = 6

x² + x - 6 = 0

a = 1 ; b= 1 ; c = -6

$Sum \ of \ roots = \dfrac{-1}{1}=-1\\\\Product \ of \ roots = \dfrac{-6}{1}=-6$

G

x²- 2x - 2 =0

a = 1 ; b = -2 ; c = -2

$Sum \ of \ roots = \dfrac{-(-2)}{1}=2\\\\Product \ of \ roots = \dfrac{-2}{1}=-2$

E

4x - 5 = -4x²

4x² + 4x - 5 = 0

a = 4 ;  b = 4 ; c = -5

$Sum \ of \ roots = \dfrac{-4}{4}=-1\\\\Product \ of \ roots=\dfrac{-5}{4}$

B

12x² +x -6 = 0

a = 12 ; b = 1 ; c = -6

$Sum \ of \ roots =\dfrac{-1}{12}\\\\Product \ of \ roots =\dfrac{-6}{12}=\dfrac{-1}{2}$

R

2x² + 5x - 25 = 0

a = 2 ; b = 5 ; c = -25

$Sum \ of \ roots=\dfrac{-5}{2}\\\\Product \ of \ roots =\dfrac{-25}{2}$

A

6x² -5x - 4 = 0

a = 6 ; b = -5 ; c = -4

$Sum \ of \ roots =\dfrac{-[-5]}{6}=\dfrac{5}{6}\\\\Product \ of \ roots = \dfrac{-4}{6}=\dfrac{-2}{3}$
