Apply Quotient Rule: To find the derivative of the function h(x), we will use the quotient rule, which states that the derivative of a function that is the quotient of two functions, v(x)u(x), is given by (v(x))2v(x)u′(x)−u(x)v′(x). Here, u(x)=x2+1 and v(x)=2x2−3x.
Find u′(x): First, we need to find the derivative of u(x), which is u′(x). The derivative of x2 is 2x, and the derivative of a constant is 0. Therefore, u′(x)=2x+0=2x.
Find v′(x): Next, we need to find the derivative of v(x), which is v′(x). The derivative of 2x2 is 4x, and the derivative of −3x is −3. Therefore, v′(x)=4x−3.
Simplify Numerator: Now we apply the quotient rule. We have: h′(x)=(2x2−3x)2((2x2−3x)(2x)−(x2+1)(4x−3)).
Subtract Terms: We simplify the numerator of the derivative:(2x2−3x)(2x)=4x3−6x2,(x2+1)(4x−3)=4x3−3x2+4x−3.So, h′(x)=(2x2−3x)24x3−6x2−(4x3−3x2+4x−3).
Final Derivative: Subtract the terms in the numerator:h′(x)=(2x2−3x)24x3−6x2−4x3+3x2−4x+3=(2x2−3x)2−3x2+3x2−4x+3=(2x2−3x)2−4x+3.
Final Derivative: Subtract the terms in the numerator:h′(x)=(2x2−3x)24x3−6x2−4x3+3x2−4x+3=(2x2−3x)2−3x2+3x2−4x+3=(2x2−3x)2−4x+3.We have found the derivative of h(x) in its simplified form:h′(x)=(2x2−3x)2−4x+3.
