Solve x^2 + x - 12 = 0
bogdanovich [222]

Answer:

x₁ = -4

x₂ = 3

Step-by-step explanation:

x²+ x + 12 = 0

x = {-1±√((1²)-(4*1*-12))} / (2*1)

x = {-1±√(1+48)} / 2

x = {-1±√49} / 2

x = {-1±7} / 2

x₁ = {-1-7} / 2 = -8/2 = -4

x₂ = {-1+7} / 2 = 6/2 = 3

Check:

x₁

-4² + (-4) - 12 = 0

16 - 4 - 12 = 0

x₂

3² + 3 - 12 = 0

9 + 3 - 12 = 0

Karolina [17]

First convert all the units into millimetres.

1 metre = 1000 millimetres

10 metres = 10000 millimetres

2 : 1000 :: x : 10000

Remember this: <u><em>Product of means is equal to the product of extremes.</em></u>

<u><em></em></u>

2 × 10000 = 1000x

20000 = 1000x

∴ x = 20000 ÷ 1000

x = 20 millimetres
