Question

need help with factoring

Answer 1

what value in place of the question mark ,makes the polynomial factor a perfect square
x^2+12x+?

Answer 2

if the coefficient of x^2 is 1 then you add the square of one half the coefficient of x to make a perfect square. For example, given x^2 + 12x you must add 6^2, getting x^2 + 12x + 6^2 = (x+6)^2.

Answer 3

so the answer would be (x+6)^2

Answer 4

yes

Answer 5

ok i got some more ?

Answer 6

ok next then

Answer 7

the graph of x^2+12x+6 can be obtained from the graph of y=x^2 by
A.shifting it 6 units to the right and 30 units down
B.shifting it 6 units to the left and 30 units up
C.shifting it 6 units to the left and 30 units down
D.shifting it 6 units to the right and 30 units up

Answer 8

sorry dont know this one

Answer 9

the polynomial 3x^2-147 has the factorization
A.3(x-7)^2
B.3x(x-49)
C.(3x-7)(3x+7)
D.3(x-7)(x+7)
