What is the rewrite of 2×2 + x – 3?
Rewrite 2 x 2 + x − 3 as ( 2 x 2 − 2 x) + ( 3 x − 3). Factor out 2x in the first and 3 in the second group. Factor out 2 x in the first and 3 in the second group.
How do you factor 2x^{2}+Ax+BX-3?
First, the expression needs to be rewritten as 2x^ {2}+ax+bx-3. To find a and b, set up a system to be solved. Factor the expression by grouping. First, the expression needs to be rewritten as 2 x 2 + a x + b x − 3. To find a and b, set up a system to be solved. Since ab is negative, a and b have the opposite signs.
What is the least common multiple of x + 2?
To add or subtract expressions, expand them to make their denominators the same. Least common multiple of x−2 and x +2 is (x− 2)(x +2). Multiply x−2x
