Which expression can go in the blank to make the equation true? -4.5 + 4.4 + ? = 0

A.) −6.7+6.8
B.) −6.7+(−6.6)
C.) 7.2 + (-7.2)
D.) 7.2 + (-7.3)
please help !!

there are many solutions.

step-by-step explanation:

step 1: simplify both sides of the equation.

4x+6=4x^2+10x−4

step 2: subtract 4x^2+10x-4 from both sides.

4x+6−(4x^2+10x−4)=4x^2+10x−4−(4x^2+10x−4)

−4x^2−6x+10=0

step 3: factor left side of equation.

−2(2x+5)(x−1)=0

step 4: set factors equal to 0.

x=-5/2 or x=1
