Answer:

None of those answers are correct

Step-by-step explanation:

There are no real solutions

Let's solve your equation step-by-step.

2+2x−3

2x+3

3x+4

x+2

Step 1: Cross-multiply.

2+2x−3

2x+3

3x+4

x+2

(2+2x−3)*(x+2)=(3x+4)*(2x+3)

2x2+3x−2=6x2+17x+12

Step 2: Subtract 6x^2+17x+12 from both sides.

2x2+3x−2−(6x2+17x+12)=6x2+17x+12−(6x2+17x+12)

−4x2−14x−14=0

For this equation: a=-4, b=-14, c=-14

−4x2+−14x+−14=0

Step 3: Use quadratic formula with a=-4, b=-14, c=-14.

−b±√b2−4ac

−(−14)±√(−14)2−4(−4)(−14)

2(−4)

14±√−28

−8

Rewrite the function by completing the square.

bixtya [17]

Answer:

$g(x) = 4(x - 2)^2 -9$

Step-by-step explanation:

Given

$g(x) = 4x^2 - 16x + 7$

Required

Complete the square

Rewrite so that $x^2$ has 1 coefficient

$g(x) = 4(x^2 - 4x) + 7$

Take half of the coefficient of x

$\frac{4}{2} = 2$

Square the result

$(\frac{4}{2})^2 = 2^2$

$(\frac{4}{2})^2 = 4$

Add and subtract the result in the bracket

$g(x) = 4(x^2 - 4x + 4 - 4) + 7$

Expand the bracket to remove -4

$g(x) = 4(x^2 - 4x + 4) - 16 + 7$

$g(x) = 4(x^2 - 4x + 4) -9$

Expand the bracket

$g(x) = 4(x^2 - 2x -2x+ 4) -9$

Factorize

$g(x) = 4(x(x - 2) -2(x-2)) -9$

Factor out x - 2

$g(x) = 4((x - 2)(x-2)) -9$

Express as square

$g(x) = 4(x - 2)^2 -9$
