Fully Factor 3x^2 – 16x + 20
ryzh [129]

Answer:

C. (3x2 - 10) (x - 2)

Step-by-step explanation:

3x^2 - 16x +20

Step 1: Sum = - 16x

Product = 60x^2

Step 2: Find 2 numbers that their sum is -16 and their product is 60. If you do that correctly, then you will get two numbers: 10 and -6

Step 3: Replace -16x with the two numbers found in step 2, then you will have; 3x^2 - 6x - 10x + 20

Step 4: Factorise the equation in step 3, like so;

(3x^2 - 6x)(- 10x + 20)

3x(x - 2) -10(x - 2)

(3x - 10)(x - 2)

To check if the answer is correct, expand the bracket: (3x - 10)(x - 2)

If the bracket is opened properly, you will get 3x^2 - 16x + 20

What is the equation of a line that passes through the points (3, 6) and (8, 4) in slope intercept form?
MrMuchimi

Answer:

y=-\frac{2}{5}x +8.4

Step-by-step explanation:

Gradient

m =\frac{y-y1}{x-x1}

m = \frac{6-4}{3-8}

m=-\frac{2}{5}

Equation of a line

(y-y1)=m(x-x1)\\

- Sub one set of points into equation

(y-6)= -\frac{2}{5} (x-6)

y=-\frac{2}{5}x +8.4
