How could I factor these
allochka39001 [22]
Ax^2 + bx + c

multiply the "a" and "c" coefficient
= ac

factor "ac" into a pair of numbers that adds to equal "b"
replace "bx" in the expression with factor pair

group terms and factor

* example problem:
2x^2 + 13x + 6

ac
2*6=12

factor pairs of 12
1*12 = 12
3*4=12
6*2=12

** The factor pair 1 and 12 add to make 13

replace 13x with (x+12x)

2x^2 + x + 12x + 6

group similar terms
(2x^2 + 12x) + (x + 6)

factor
2x(x + 6) + (x + 6)

The same parenthesis (x + 6) can be factored further by combining the outside multipliers 2x and 1

= (2x + 1)(x + 6)

Nick and June win some money and share it in the ratio 4:5. Nick gets £40. How much did June get?
sineoko [7]

Answer:

June gets \£50

Step-by-step explanation:

Let

x ----> amount of money Nick gets

y ----> amount of money June gets

we know that

\frac{x}{y}=\frac{4}{5} -----> equation A

x=40 ----> equation B

solve the system by substitution

substitute equation B in equation A

\frac{40}{y}=\frac{4}{5}

solve for y

Multiply in cross

(40)(5)=y(4)\\y=200/4

y=\£50
