Answer 2

What do you think? What did you get after working it out?

Answer 3

Answer 4

First ask your self what two factors when you times them equals 18 and also sums(add together) up to -9

Answer 5

to find x-intercept ...let y = 0

Answer 6

so solve
x^2 - 9x + 18 = 0

Answer 7

i got (0,3) and (0,6)

Answer 8

dont u think it should be (3 , 0) and (6 , 0)???

Answer 9

to find x - intercept let the y = 0
(x^2-9x+18) = 0 so the y's have to be 0
you are solving for the x values

Answer 10

consider the 2 numbers 6 and 3. Those numbers work because
6 x 3 =18 (got my last term)
6+3 =9 (got my middle term)
so now we can factor
(x-6)(x-3) =0
so now we have 2 cases
x - 6 =0 and x -3 =0
solve for x and we should have what @rishavraj said

Answer 11

the y is fixed at 0 for these cases... since we are looking for x-intercept
