Solve the following by factoring. 12x^2 -7x -12 = 0
nirvana33 [79]

Solution:

The given equation is

12x^2 -7x -12 = 0

Now we will factor the middle term as per the ac-method because the given equation is a quadratic equation.

12x^2 -7x -12 = 0\\\\12x^2-16x+9x-12=0\\\\4x(3x-4)+3(3x-4)=0\\\\(3x-4)(4x+3)=0\\\\3x-4=0,or, 4x+3=0\\\\x=\frac{4}{3},x=\frac{-3}{4}\\

The two inequalities √4<√5<√√55 and √8<2.9<√√9. are true.

√4<√5<√√55  → 2 < 2.23 < 7.41

√8<2.9<√√9    → 2.82 < 2.9 < 3

Therefore correct answers is option C and option E which are √4<√5<√√55 and √8<2.9<√√9.

Two lines, C and D, are represented by the equations given below:
lys-0071 [83]
Bought lines need to pass same point, so:

x+12 = y    =    y = 3x+2
x+12=3x+2     |-2
x+10=3x         |-x
10=2x             |/2
5=x
x+12 = y   => 5+12 = y =>y = 17

(x,y) => (5,17)
