Which equation has non real solutions
A: 2x^2+4x-12=0
B:2x^2+3x=4x+12
C:2x^2+4x+12=0
D:2x^2+4x=0

Step-by-step explanation:

hello :

help : ax²+bx+c=0 ( a≠ 0 )

calculate : Δ = b²-4ac    if Δ<0 you have non real solutionscontinu

the answer to the question is a

step-by-step explanation:

it has the same slope and the same y-intercept.

y + 11 = -7/9(x - 18)

y + 11 =-7/9x + 14

b

y = -7/9x + 3

y-intercept (0, 3)

false

step-by-step explanation:

4y - 6 + 4y^2 - 9

before simplifying this contains 4 terms

after simplifying

4y -15 + 4y^2

it contains 3 terms
