Pulling out like terms
3.1 Pull out like factors :
-3x2 + 12x - 8 = -1 • (3x2 - 12x + 8)
Trying to factor by splitting the middle term
3.2 Factoring 3x2 - 12x + 8
The first term is, 3x2 its coefficient is 3 .
The middle term is, -12x its coefficient is -12 .
The last term, "the constant", is +8
Step-1 : Multiply the coefficient of the first term by the constant 3 • 8 = 24
Step-2 : Find two factors of 24 whose sum equals the coefficient of the middle term, which is -12 .
-24 + -1 = -25
-12 + -2 = -14
-8 + -3 = -11
-6 + -4 = -10
-4 + -6 = -10
-3 + -8 = -11
-2 + -12 = -14
-1 + -24 = -25
1 + 24 = 25
2 + 12 = 14
3 + 8 = 11
4 + 6 = 10
6 + 4 = 10
8 + 3 = 11
12 + 2 = 14
24 + 1 = 25
Answer:
480
Step-by-step explanation:
All you have to do is multiply all the numbers together.
12 * 4 * 5 * 2 = 480

Total amount = $520
Sharing Ratio = 2 : 4 : 7

First Student Ratio : 2
Second Student Ratio : 4
Third Student Ratio : 7
Total Quantities of ratio = 2 + 4 + 7 = 13
<u>Formula</u><u> </u><u>applied</u><u> </u><u>:</u><u> </u>
Share = Ratio of Student / Total quantities of ratio × Total amount
First Student share :
= 2/13 × 520
= $80
Second student share:
= 4/13 × 520
= $160
Third Student share :
= 7/13 × 520
= $280 .
Proof :
Total share = $520
( 80 + 160 + 280 )= $520
$520 = $520
