12x * 4x2 = 48x3
4x2 - 12x + 9 = 5; whence, 2x - 3 = ±√5, and 2x = 3 ±√5. Therefore, x = ½ (3 ±√5).
If you mean: 4x squared+12x+9 then it is (2x+3)(2x+3)
4x2 - 12x + 9 = 4x2 - 6x - 6x + 9 = 2x(2x - 3) - 3(2x - 3) = (2x - 3)(2x - 3) or (2x - 3)2
it means that instead of having (2x-3)2 you write 4x2-12x+9
12x * 4x2 = 48x3
4x2 + 12x + 5 = (2x + 1)(2x + 5).
4x2 = -12x, divide both sides by 4x: x = -3
4x2+12x = 4x(x+3) when factored
4x
Only if the value of c is 9 because:- 4x2+12x+9 = (2x+3)(2x+3)
There are four solutions to 9x4 plus 27x3 - 4x2 - 12x equals 0. One of the solutions is x = -3.
The area is 4x2 square units
4x2 - 12x + 9 = 5; whence, 2x - 3 = ±√5, and 2x = 3 ±√5. Therefore, x = ½ (3 ±√5).
To find an area of a rectangle, take the length and width and multiply the two together. In your case the length is 4, the width is 2, find the product... so 4 x 2 = 8. Thus the area of the rectangle is 8 units squared. It's perimeter is 12, which means 2l x 2w or 2(length) x 2(width) = 2(4) x 2(2) = 12.
4x2 is 8+ 12x + 3 collect like terms, 8+3= 11, 12x+11 to solve for x, transpose the 11 to the other side of the = sign, 12x=-11, divide by 12, x=-11/12
not necessarily. take the example of a 3x3 square and a 4x2 rectangle. Both have a perimeter of 12. but the square has an area of 9 and the rectangle has an area of 8.
