Answer 1

sum of middle term = -20
and product of trem broken = -32

Answer 2

can u do that??

Answer 3

can you please solve?

Answer 4

i can guide

Answer 5

well use quadratic formula

Answer 6

u know abt that??

Answer 7

are you sure about the question ?
you won't be getting integer solutions
so you cannot split middle term

Answer 8

yeah i know about it

Answer 9

can u apply it for finding x

Answer 10

use quadratic formula or completing the square method
whichever you're comfortable with

Answer 11

but i have forgotten the quadratic formula

Answer 12

Compare your quadratic equation with \(ax^2+bx+c=0\)
find \[a=...?\\b=...?\\c=...?\\\] \[ \\ \sqrt{b^2-4ac}=...?\]
then the two roots of x are:
\(\huge{x_{1,2}=\frac{-b \pm \sqrt{b^2-4ac}}{2a}}\)

Answer 13

can you guide me how to put values
in that

Answer 14

first find a,b,c

to simplify calculations, you can also factor -2 initially from your equation

Answer 15

okay i am working on it

Answer 16

thnx for your help

Answer 17

\(-2 (x^2+10x-8)\)

compare
x^2+10x-8
with
ax^2 +bx+c

Answer 18

a=-2, b=20,c=8

Answer 19

no..

you're taking
x^2+10x-8
right ?

Answer 20

yeah
