Question

8xsqare+18x+7=0
answer my question

Answer 1

Step-by-step explanation:

8x²+18x+7=0

8x²+4x+14x+7=0

4x(2x+1)+7(2x+1)=0

(4x+7)(2x+1)=0

Answer 2

$by \: factorization \\ 8x {}^{2} + 18x + 7 = 0 \\ 8x {}^{2} + 14x + 4x + 7 = 0\\ 2x < 4x + 7 > + 1 < 4x + 7 > = 0\\ < 4x + 7 > \: \: \: < 2x + 1 > = 0 \\ 4x + 7 = 0 \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: 2x + 1 = 0 \\ 4x = - 7 \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: 2x = - 1 \\ x = \frac{ - 7}{4} \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: x = \frac{ - 1}{2}$
