3x^2-12x factorise in the form (x+b)(x-b)
Alekssandra [29.7K]

Answer:

3x(x-4)

Step-by-step explanation:

3x^2-12x  cannot be factorised in the form (x+b)(x-b) unless one of the b's is zero, so I wonder if the expression is incomplete?

To factorise 3x^2-12x, take out the common factor 3x:

\implies3x(x-4)

Therefore, x = 0 and x = 4

- - - - - - - - -

3x^2-12x  factorised in the form (x+b)(x-b) would be (3x+0)(x-4)

but it is not usual to have a zero in a factorised form.

A river 3m deep and 40 m wide is flowing at the rate 2km /h . how much water will fall into the sea in a minute.​
Alex

Answer:

Area of river = 3 × 40

= 120 {m}^{2}

amount of water that falls into the sea ⇒

= Area × rate

= 120 × 2 \frac{km}{hr}

= 120× \frac{2000  m}{60  min}

= 2 × 2000

= 4000 m  ^{3}

∴4000m  ^{3} of water falls into the sea permin.
