Q. Subtract. Simplify your answer.(r3−9r2+3r)−(8r3−8r2+3r−7)◻
Write Polynomials to Subtract: First, let's write down the polynomials we need to subtract: r^\(3 - 9r^2 + 3r) - (8r^3 - 8r^2 + 3r - 7)\
Distribute Negative Sign: Now, distribute the negative sign to the second polynomial: r^\(3 - 9r^2 + 3r) - 8r^3 + 8r^2 - 3r + 7\
Combine Like Terms: Next, combine like terms by subtracting the coefficients of the same powers of r:r3−8r3=−7r3−9r2+8r2=−r23r−3r=0rAnd don't forget the constant term at the end: +7
Write Simplified Polynomial: Now, write down the simplified polynomial: −7r3−r2+7
