Answer: 2(x+5)2+ 8x + 5+6=0

Step-by-step explanation:

2(x + 5)2 + 8x + 5 + 6=0

2(x+5)(x+5) + 8x + 11=0

2(x^2+ 10x + 25) + 8x + 11=0

2x^2 +20x + 50 + 8x + 11=0

2x^2 +28x +66=0

This is a second-degree equation, the greatest power is two. Hence it is a quadratic equation.

Please help on this question.

Sonbull [250]

Answer:

Step-by-step explanation:

$\frac{ - 20 {x}^{2} + 14x + 12}{5x - 6} \\ \\ = \frac{- (20 {x}^{2} - 14x - 12)}{5x - 6} \\ \\ = \frac{ - (5x - 6)(4x + 2)}{5x - 6} \\ \\ = - (4x + 2 ) \\ = - 4x - 2$

Domain:

g(x) ≠ 0

$5x - 6 = 0 \\ 5x = 6 \\ \\ x = \frac{6}{5}$

All real numbers ≠ 6/5
