(sqrt3 + 5)(sqrt3 3) ?
multiply that out
sqrt3*sqrt3 3sqrt3 +5sqrt3 15
now combine and simplify terms.
yes the problems is:
((sqrt3)+5)((sqrt3)3)
if i put in my calculator what the squareroot of 3 it will give me 1.7
so if i it by decimals i get the follwoing
2.895.1+8.515 is this right becuase i need to do foil for it correct or no.
NNNNOOOO. don't put it in the calculator.
multiply that out
sqrt3*sqrt3 3sqrt3 +5sqrt3 15
now combine and simplify terms.
sqrt3*sqrt3 is 3. The two middle terms add to 2sqrt3
So the answer is 2sqrt3 12.
