Answer:
{ (-2,2) , (0,2) , (7,2) , (11,2) }
Step-by-step explanation:
Your x variable cannot repeat.
A = 9 b = -5
45 = 4a + 2b +c
45 = 4(9) + 2(-5) + c
45 = 26 + c
19 = c
First you do 2 times 2 which is 4 and then takeaway 1 of you answer which makes it
4
X² <span>+ 11x = -28
to find the solution of this polynomial, it'll be easiest to try and factor it. the first thing you need to do is move everything to one side:
</span>x² + 11x = -28 ... add 28
x² + 11x + 28 = 0 ... factor
(x + 7)(x + 4) = 0 ... now set both of your factors equal to zero and solve for x
x + 7 = 0
x = -7
x + 4 = 0
x = -4
