write as a square of a binomial

step-by-step explanation:

graph using a few selected

x         y

-1       15

0         6

1         2.4

2       0.96

n=1.75+1.75

step-by-step explanation:

3.5/2=1.75

option (a)

step-by-step explanation:

step 1:   take 2 number whose product equal to 25..

and sum of those two number are -10

step: 2 for example here if we take 5,5 are the number,,

5*5=25

and

5+5=10

but we need -10

so if we take   -5,-5

so -5*-5=25

and -5+(-5)=-10

s0

come the equation

replace -10x by these number

like -5x -5x+25

take common

x(x-5)-5(x-5)=0

(x-5)(x-5)=0
