(4x^2 + 8x + 15) + (x^2 x 27) (x + 5)(x 7)

Type your math problem... (4x^2 + 8x + 15) + (x^2 - x - 27) - (x + 5)(x - 7)

Question

(4 x^{2} + 8 x + 15) + (x^{2} - x - 27) - (x + 5) (x - 7)

Simplify the expression

4 x^{2} + 9 x + 23

Show Solution

x_{1} = - \frac{9}{8} - \frac{287}{8} i, x_{2} = - \frac{9}{8} + \frac{287}{8} i

Alternative Form

x_{1} \approx - 1.125 - 2.117634 i, x_{2} \approx - 1.125 + 2.117634 i
