A quadratic equation y=x2+2x+6 does not have a real solution. State whether the statement is true or false.
True
False
When we plot the graph of y=x2+2x+6, it does not intersect the x-axis. So, it does not have a real solution.
3x + 7 is a rational expression. State whether the statement is true or false.
If xa = xb, then a = b. State whether true or false.
