Answer:

Step-by-step explanation:

21-6x-19-20+5x=24-18x-9x+20-5x distribution property

-x-18=44-32x common factors

31x-18=44 add 32x to both sides

31x=62 add 18 to both sides

x=2 divide 31 to both sides(equals 2) so x equals 2

Answer:

x=2

Step-by-step explanation:

3(7-2x)-19-5(4-x) = 3(8-6x)-9x+5(4-x)

or, 21-6x-19-20+5x = 24-18x-9x+20-5x

or, 21-19-20-6x+5x = 24+20-18x-9x-5x

or, -18-x = 44-32x

or, -x+32x = 44+18

or, 31x = 62

or, x = 62/31

or, x = 2

Factor 16x^2 + 49. Check your work.

Shtirlitz [24]

Answer:

$16x^2+49=(x-\frac{7i}{4})(x+\frac{7i}{4})$

Step-by-step explanation:

Given : Expression $16x^2+49$

To find : Factor the expression ?

Solution :

The given expression is a quadratic function $y=ax^2+bx+c$ the solution is $x=\frac{-b\pm\sqrt{b^2-4ac}}{2a}$

On comparing with general form,

a=16, b=0, c=49

Substitute in the formula,

$x=\frac{-0\pm\sqrt{0^2-4(16)(49)}}{2(16)}$

$x=\frac{\pm\sqrt{-3136}}{32}$

$x=\frac{\pm56i}{32}$

$x=\frac{56i}{32},\frac{-56i}{32}$

$x=\frac{7i}{4},\frac{-7i}{4}$

Factors are $(x-\frac{7i}{4}),(x+\frac{7i}{4})$

Therefore, $16x^2+49=(x-\frac{7i}{4})(x+\frac{7i}{4})$
