add 3 to both sides
x2 -3(+3) =162 (+3)
x2 = 165
x ~ +- 12.84
(-x)2 = 3=> -x = ±√3=> x = -√3 and x = √3
3x^2 + 5x - 8 = 0 + 8 + 8 3x^2 + 5x = 0 8x ^2 = 0
3x2 - 11x - 4 = 0(3x + 1)(x - 4)x = -1/3 and 4
5
Add 2.9 to both sides. y = 8.2
It is: 9-4 = 5
That factors to (x + 1)(x - 3) x = -1, 3
(-x)2 = 3=> -x = ±√3=> x = -√3 and x = √3
3x^2 + 5x - 8 = 0 + 8 + 8 3x^2 + 5x = 0 8x ^2 = 0
By factoring I get x-3 divided by x+3
3x2 - 11x - 4 = 0(3x + 1)(x - 4)x = -1/3 and 4

Forty-three minus nine equals 34.
If you are looking for the zeros of this function: x = -2 plus or minus 2 X the square root of 5.
Three fourths minus three sixths equals one fourth
Add 2.9 to both sides. y = 8.2
it equals 5
