Answer:
Prime
Step-by-step explanation:
x² + 20x − 36
You must find a pair of numbers that multiply to give -36 and add to give +20.
The likely candidates are 2 and 18, and they must have opposite signs to give a negative product.
+2 × (-18) = -36; +2 + (-18) = -16
-2 × 18 = -36; -2 + 8 = +16
Neither combination gives +20 as the sum.
The expression can't be factored with rational numbers.
The expression is prime.

Express in standard form
To do this, we simply reorder the terms of the polynomial in descending order of power.
So, we have:
So firstly, find minus 1600 by 96 which = 1504 then divide 1504 by 1600 then times by 100 the percentage is = to 94%
