______
x = −
0. 142857
Step-by-step explanation:
X^2+x-30 -- find two numbers that add to one and multiply to -30, which would be 6 and -5. so now you have x^2+6x-5x-30. factor out x and 5 to get x(x+6)-5(x+6). so you get (x+6)*(x-5)
15/7 is approximately 2.143
I think it’s the last one but I’m not sure. Let me know if you get it right.
