The first is C. The second is A.
No, in order for this to be correct, you'd have to move BOTH decimals in the same direction the same amount of places.<span />
Hello,
x^3+7x^2+10x-6=x^3+3x^2+4x^2+12x-2x-6
=x²(x+3)+4x(x+3)-2(x+3)
=(x+3)(x²+4x-2)
=(x+3)(x+2-√7)(x+2+√7)
zeroes={-3,-2+√7,-2-√7}
D is the answer to the question
