can i get some help with #6
Just break it up 4x^2 needs to equal 240 So find what equals 240 when multiplied by 4
4(x^2) + 2 - (242) ➡0 (2^2 x^2 + 2) - 242 ➡0 4 (x^2 - 60) Now factor: x^2 -60 4 (x^2 - 60) ➡0 4 ➡0[solve] x^2➡±60 [by the way] X ➡ ± √15 [⬅this might be your answer if you're working with square roots]
