Mulitply the binomials and identify the value of "B" in the product. (−2x + 3)(x + 8) = −2x2 −Bx + 24 {"version":"1.1","math":"Mulitply the binomials and identify the value of "B" in the product. (-2x + 3)(x + 8) = -2x2 -Bx + 24"}
Question 6 options:
for (c+d)(ex+f) the expanded form is dex^2+dex+cfx+df (ce)x^2+(de+cf)x+(df) ax^2+bx+c the value of a is ce the value of b is de+cf the value of c is df
so
(-2x+3)(x+8) (-2x+3)(1x+8) b is 3*1+-2*8=3-16=-13
answer is -13 so pick 13 because we have -B, so B=13
