Find the value of "m" that gives infinitely many solutions ! PLEASE HELP!!
Gre4nikov [31]

Answer: 2x

Step-by-step explanation: 18+2(x-7)=4+M. First distribute 2 to (x-7), then you will be left with 18+2x-14=4+M. You can further simplify the left side of the equation by subtracting 14 from 18, now you are left with 2x+4=4+M. Subtract 4 from both sides to solve for M, 2x=M.

juin [17]

The factors of the expression are \rm(3 - 7x^2)(x - 3)

<h3>How to find factors in the expression?</h3>

First group the first two terms and the last two terms together respectively.

The factors of the expression are given by;

\rm= -7x^3 + 21x^2 + 3x - 9\\\\=-7x^2(x - 3) + 3(x - 3)\\\\=(3 - 7x^2)(x - 3)

Hence, the factors of the expression are \rm \rm(3 - 7x^2)(x - 3).
