We have two numbers say a, b. And a system of equations.
It looks a bit intimidating but it's actually very easy.
Instead of term a + b in the second equation we can say it's zero because the first equation describes a + b as being equal to 0.
So,
The above equation is not true therefore numbers a and b do not exists in the real number domain.
No solution.
Hope this helps.
Easy, the difference between 72 and 90 is 18, so you just take 18 divided for 72 to get the percent change which equal 0.25 or 25%. Hoped it help!
Answer
The difference is -5
Because
In the number line
-3 is in the negative side and
2 is in the positive side
So difference means minus
So,
-3-2
=-5
Remember
- - = + (but the answer should have - sign)
- + = - (the greatest number's sign will be taken)
++ = -
+ - = -

Answer:
(2x-1)(x+5)
Step-by-step explanation:
Given the equation (2x² + 9x-5=0, we are to factorize it
2x² + 9x-5=0
2x² + 10x-x-5=0
2x(x+5)-1(x+5) = 0
(2x-1)(x+5)
Hence the factorized form of the equation is (2x-1)(x+5) = 0
