Sir ,how many roots of the equation ----x^2+y^3=6
Sir please make a video on how to understand word problems
To understand word problems:
Step 1: scan the problem statement for all given numbers. Every time you see a number, write it down, with units. Organize your given information by category of given information.
Step 2: look for hidden numbers, such as numbers written in letters (e.g. three), and terms like "a" or "both" that indirectly imply a number. Organize these in your list of given information.
Step 3: Write down enough context to tell what each piece of given data means
Step 4: Identify numbers you don't know, but want to find. Also identify information you'd like to know as an intermediate step, but weren't given. Assign variable names to all unknowns.
Now you have your groundwork laid. Look for relationships between the given data, and between the given data and the unknowns. Look for words that would imply math operations (such as total for addition and difference for subtraction), as these are clues for what operation should apply. Construct equations based on this information.
Construct equations until you have as many equations as you have unknowns. A linear system of independent equations (i.e. neither redundant nor contradictory), will have a single unique solution if there's as many equations as unknowns. Non-linear systems can have multiple solutions, and usually only one applies to the word problem.
