Question

Solve the following equation....
3x(x+5)-x(x+6)=2


pls help me... ​

Answer 1

Answer:

x = -7/2

Step-by-step explanation:

$3x(x + 5) - x (\: x + 6) = 2$

$3x {}^{2} + 15x \: - x {}^{2} - 6x = 2$

$2x {}^{2} + 9x = 2$

$2x {}^{2} = 2 - 9x$

${x}^{2} = 2 - 9x \div 2$

$x {}^{2} \div x = 2 - 9 \div 2$

$x = - 7 \div 2$

Therefore x = -7/2
