Question

write the coordinate of the reflection of the following. a) ( -7, -2 ) in the y - axis b) ( 4, -2) in the x - axis.​

Answer 1

Answer:

p(x)=x  

2

−x−6

=x  

−3x+2x−6

=x(x−3)+2(x−3)

=(x−3)(x+2)

=(x−3)(x+2)

∴ The value of p(x) is zero when x=3 or x=−2

∴ Sum of the Zeroes =3−2=1 =−  

1

−1
