As i see it
It’s pretty forward, logically only A is possible
Step-by-step explanation:
its either you explain it wrong or the answer is jenny doesn't need to spend anymore money to have more baseball cards then you because she already has more then you.
You bought baseball cards at $8 for 12 cards and added them to your collection of 128 baseball cards
128+12=140
Jenny bought baseball cards at $6 for 8 and added them to her collection of 150 baseball cards
150+8=150
150>140
First we note symmetry in the expression's coefficients.
We also note that 7*3=21, and 7+3=10.
From the rational roots theorem, we are tempted to try with 3 and 7 as coefficients of the factors.
Try
(7b+3)(3b+7)=21b^2+(49+9)b+21
By switching the sign of 3b+7 to 3b-7, we get the signs right, to check:
(7b+3)(3b-7)=21b^2+(9-49)b-21=21b^2-40b-21 ....right!
So
(7b+3)(3b-7)=21b^2-40b-21
