The first few steps in solving the quadratic equation 5x2 + 27x = 14 − 13x by completing the square are shown. 5x2 + 27x = 14 − 13x 5x2 + 40x = 14 5(x2 + 8x) = 14 Which is the best step to do next to solve the equation by completing the square: 5(x2 + 8x + 16) = 305(x2 + 8x + 16) = 945(x2 + 8x + 4) = 185(x2 + 8x + 4) = 34
Accepted Solution
A:
5(x^2+8x)=14 5(x^2+8x+16)=5(x^2+8x)+5*16=5(x^2+8x)+80=14+80=94 The corect answer is the second
