That equation would be right because it says solve for p. you would put p where the q is because that is the variable you need to find the answer to. and since the equation wants you to multiply you would divide when the q is switched with p so that is how you get p=q/r+s

Answer:
x= -1
Step-by-step explanation:
p= x² +4x -2 -----(1)
q= 2x -1 ------(2)
q -p= 2 -----(3)
Substitute (1) and (2) into (3):
2x -1 -(x² +4x -2)= 2
2x -1 -x² -4x +2= 2 <em>(</em><em>Expand</em><em> </em><em>bracket</em><em>)</em>
-x² -2x +1=2 <em>(</em><em>S</em><em>implify</em><em>)</em>
x² +2x +2 -1= 0 <em>(</em><em>Bring</em><em> </em><em>all</em><em> </em><em>terms</em><em> </em><em>to</em><em> </em><em>one</em><em> </em><em>side</em><em>)</em>
x² +2x +1= 0
(x +1)²= 0 <em>(</em><em>Factorise</em><em>)</em>
x +1= 0 <em>(</em><em>Square</em><em> </em><em>root</em><em> </em><em>both</em><em> </em><em>sides</em><em>)</em>
x= -1 <em>(</em><em>-1</em><em> </em><em>on</em><em> </em><em>both</em><em> </em><em>sides</em><em>)</em>
(1. -2) (2. 0) (3. 6) (4. 3)
