Solving x (3x-2) = 5-8x by formula method

Solving x (3x-2) = 5-8x by formula method

x(3x-2)=5-8x
3x^2-2x=5-8x
3x^2+6x-5=0
△=6^2+4*3*5=96
√△=√96=4√6
x1=(-6+4√6)/6=(-3+2√6)/3
x2=(-3-2√6)/3

X (2X-4) = 5-8x

The solution of equation 3x-8x + 2 = 0 is obtained by formula method?

x1,2=[8±√(64-24)]/6
=(4±√10)/3

The tangent slope of function y = square of X + X + 4 at point (1. - 4) gives the following process

Derivation: y '= 2x + 1
Because x = 1, y '= 2 * 1 + 1 = 3
So the slope is 3

3x / 4 + 1x / 5 = 7 / 8
process

6 * 5-2 / 1 x = 18 4 / 3 x = 2 / 5 2-15 / 8 x = 10 / 17 6 + (3 / 15 + 20%) x = 84 3.7-30% = 5 / 8

X = 24, x = 6, x = 9 / 16, x = 210, the last one is not X. I guess if it is 3.7-30% = 8 / 5, it should be x = 17 / 8

To solve the equation, (1) 1 / 3 x + 3 / 4 x = 26 / 5 (2) 3 / 4 x = 12-9 (3) 2 / 3 + x = 4 and 1 / 2
solve equations.
(1) 1 / 3 x + 3 / 4 x = 26 / 5
(2) 3x = 12-9
(3) 2 / 3 + x = 4 and 1 / 2
(4) X-2 / 5 = 16 × 2

It's too easy. I'll take you
