Answer 5

\[2x^2+x-3\]First separate the first number into a product of two,\[2x\]\[x\]Then find two numbers that multiplied together give you the last number (-3),\[3* -1\]or\[-3*1\]Now, find which pair adds up to the coefficient in the middle (1), considering the 2 as a factor for one of them,\[3+(-1*2)=3-2=1\]So the pair that works is,\[3,-1\]Now add them to the two products you made in the first step,\[2x+3\]\[x-1\]Which is the answer for A.
