Factorise 9f²-12f plus 4​
Komok [63]

Answer:

(3f - 2)²

Step-by-step explanation:

Given

9f² - 12f + 4

Consider the factors of the product of the coefficient of the f² term and the constant term which sum to give the coefficient of the f- term.

product = 9 × 4 = 36 and sum = - 12

The factors are - 6 and - 6

Use these factors to split the f- term

9f² - 6t - 6t + 4 ( factor the first/second and third/fourth terms )

= 3f(3f - 2) - 2(3f - 2) ← factor out (3f - 2) from each term

= (3f - 2)(3f - 2)

= (3f - 2)²

Mekhanik [1.2K]

Answer:

A) 32y³ + 24y² - 12y - 9

Step-by-step explanation:

(-8y² + 3)(-4y - 3) = (-8y² x -4y) + (-8y² x -3) + (3 x -4y) + (3 x -3)

                           = 32y³ + 24y² - 12y - 9

3x+4=-5x-3+15, what are some of the steps that should be taken to solve for x? Select all that apply.
tino4ka555 [31]
3x+4=-5x-3+15
First combine like terms:
3x+4=-5x+12
Get x on one side:
3x+4=-5x+12
-3x -3x
4=-8x+12
Next get x by itself:
4=8x+12
-12 -12
-8=8x
Now divide one more time to get x by itself since 8x is 8 times x and we must do the opposite (÷).
-8/8=8x/8
-1=x ---> x=1
