Do you mean x^2+4x+3 or x^2-4x+3?
x^2+4x+3 = (x+1)(x+3)
x^2-4x+3 = (x-1)(x-3)
l 2x + 6 l - 4 = -20
l 2x + 6 l + 16 = 0
2x + 22 = 0
x + 11 = 0
x = -11
Am i wrong?
LaTeX: Use the \over or \frac command
Calculator: just type a/b as a÷b
6. (16x^2y^-4z^-1)^0/y^2 = 1/y^2
8. Anything to the power of 0 is 1
Therefore equals to 1
10. \({{a}^{{2b}^{3}}}^{-1}= \frac{1}{{{a}^{{2b}^{3}}}}\)
Btw the question numbers i mentioned are Pythagorean triples xD
(((7000000000/46%)/.17%)/5.52%)
= (((7000000000÷0.46)÷0.0017)÷0.0552)
= 7000000000÷0.46÷0.0017÷0.0552
= 162163163942325.5124355980573316286232
The answer is 145,153,076
When 2<x<5
it's equal to 9 1/4 which is 37/4
(1+50)(50)/2
=1275
10 1/2 x 15 1/8
= 21/2 x 121/8
= (21x121)/(2x8)
=2541/16
=158 13/16
