Add or subtract (4x^2-2x-1)-(-3x^3+2)

HEYYAA

Step-by-step explanation:4x^2-2x-1-(-3x^3+2)

so as to opent the bracket the signs should be changed

so it becomes4x^2-2x-1+3x^3-2=+3x^3+4x^2-2x-3 i sthe answer

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
