(2x - 7)(x - 2)
14*13=182
14*12=168168+41=209
The LCM is 1,890
84
14 x 7 = 28 + 70 = 98
134
14+14+40+40=108
The answer is 70. Simply add the numbers together like you would for two plus two. To check your work, a calculator is the best option.
When factoring it is fairly easy to check your answer. Say we want to factor x2+9x+14=0 (x+7)(x+2)=0 now if we want to check then we can just multiply these together and we should get the original polynomial... x2+2x+7x+14=0 x2+9x+14=0
9,986 plus 14 = 10,000
14 + 14 = 28
