Answer

b

−3 and 4-3 \text{ and } 4

Step-by-step solution

2 steps

Step 1: Determine the values of bb and cc for x2+x−12x^2 + x - 12.
The general form of a trinomial is ax2+bx+cax^2 + bx + c.
Comparing x2+x−12x^2 + x - 12 to ax2+bx+cax^2 + bx + c:
a=1a = 1
b=1b = 1
c=−12c = -12

Part a

The value of bb is 1\boxed{1}.

Part b

−3 and 4-3 \text{ and } 4

The value of cc is −12\boxed{-12}.

  1. Complete the table for finding integers rr and ss for x2+x−12x^2 + x - 12.

    We need two integers rr and ss such that their product r×s=c=−12r \times s = c = -12 and their sum r+s=b=1r + s = b = 1.

    Factors of -12Product of the two factorsSum of the two factorsResult
    1 and −12-121×(−12)=−121 \times (-12) = -121+(−12)=−111 + (-12) = -11Not 1
    −1-1 and 12−1×12=−12-1 \times 12 = -12−1+12=11-1 + 12 = 11Not 1
    2 and −6-62×(−6)=−122 \times (-6) = -122+(−6)=−42 + (-6) = -4Not 1
    −2-2 and 6−2×6=−12-2 \times 6 = -12−2+6=4-2 + 6 = 4Not 1
    3 and −4-43×(−4)=−123 \times (-4) = -123+(−4)=−13 + (-4) = -1Not 1
    −3-3 and 4−3×4=−12-3 \times 4 = -12−3+4=1-3 + 4 = 1Is 1

    The two integers are −3 and 4\boxed{-3 \text{ and } 4}.

  2. Show the mathematical steps for factoring x2+x−12x^2 + x - 12.
