Help 10 points Rewrite the equation by completing the square. 4x^2-12x+9 =0

1 answer:

3 0

Answer:

You can rewrite this equation by using identity:

4x² - 12x + 9 = 0

2²x² - 2 × 2 × 3x + 3² = 0

(2x - 3)² = 0

*Just in case you want to know, x is equal to 3/2

When you multiply by 1/10 you normally add another 0:
1/10 * 0.092=0.0092

$y=2x^2+8x-9\\D=b^2-4ac\\D=64-4(2)(-9)\\D=64+72 > 0$

There are 2 roots so the only way to complete the square is,

$y=2x^2+8x-9\\y=2[(x^2+4x)]-9\\y=2[(x^2+4x+4)-4]-9\\y=2[(x+2)^2-4]-9\\y=2(x+2)^2-8-9\\y=2(x+2)^2-17$

Just factor 2 out of 2x^2+8x (just ignore the -9) then find the number that will make the terms be able to complete the square.

then complete the square and multiply 2 inside the brackets.

subtraction as you already get the vertex form and know how to complete the square.

Vertex Form: $y=2(x+2)^2-17$

Pretty sure it’s 65 since its alternate interior angles which equal 180
