In this week, we learned about equations of lines. 1.y=mx+b ( Slope y– intercept form) 2.Ax+By+C=0 (General Form) 3.y-y1=m(x-x1) eg: 8x-3y-3=0 (General form) and we are looking for the slope and y- intercept -3=-8x+3 3y=8x-3Continue reading

we learned many things so far, but especially I had to review about Exponents Basic Formulas (1) am×an=am+n a2×a3=a2+3=a5 (2) am÷an=am−n a5÷a2=a5−2=a3 (3) (am)n=amn (a3)2=a3×2=a6 (4) (ab)n=anbn (ab)3=a3b3 (5) ( ab)n = anbn ( ab)3 = a3b3 a0 =Continue reading

At first, you think about first half of the question, I mean -4(a2+5) it is going to be (-4a2-20) and add the rest of the equation. then you just multiply numbers from -4a2 (3a2-a-7) then,Continue reading
