Find the representation of the product of the following function
f(x)=x2−5x−50
To solve this problem, we will factor the quadratic function f(x)=x2−5x−50 into two binomials:
- Step 1: Identify the values of a=1, b=−5, and c=−50 in the quadratic expression ax2+bx+c.
- Step 2: We look for two numbers that multiply to c=−50 and add up to b=−5.
- Step 3: Consider the factor pairs of −50. Possible pairs include (−1,50), (1,−50), (−2,25), (2,−25), (−5,10), and (5,−10).
- Step 4: The correct pair is (5,−10) because 5×(−10)=−50 and 5+(−10)=−5.
- Step 5: Express f(x) in its factored form using these numbers: f(x)=(x+5)(x−10).
- Step 6: Verify the factorization by expanding: (x+5)(x−10)=x2−10x+5x−50, which simplifies to x2−5x−50, confirming correctness.
Therefore, the correct factorization of the quadratic f(x)=x2−5x−50 is (x+5)(x−10).
Thus, the product representation of the function is (x+5)(x−10).
(x+5)(x−10)
