3(r+2s)=2t-4
a⋅(b-2)=3b

Question

$$[(3x+6)- \sqrt{ 5x-2 } ][(3x+4)+ \sqrt{ 5x-2 } ]$$

Answer

[3*x+10-x*sqrt(5*x-2)][3+sqrt(5*x-2)]

Solution


Remove parentheses.
\(3x+6-\sqrt{5x-2}\)\(3x+4+\sqrt{5x-2}\)
Regroup terms.
\(3x+6-x\sqrt{5x-2}\)\(3+4+\sqrt{5x-2}\)
Collect like terms.
\(3x+(6+4)-x\sqrt{5x-2}\)\(3+\sqrt{5x-2}\)
Simplify.
\(3x+10-x\sqrt{5x-2}\)\(3+\sqrt{5x-2}\)
