4x2-x+2x2 is 6x2-x when simplified
12x * 4x2 = 48x3
4x2 - 30 = 34 ⇒ 4x2 = 64 ⇒ x2 = 16 ⇒ x = 4 or -4
4x2 - 30 = 34 Add 30 to both sides 4x2 = 64 Divide both sides by 4 x2 = 16 Take the square root of both sides: x = 4 or -4
Divide all terms by 4:- x2+7x+12 = (x+3)(x+4) when factored
Given 3x3 + 4x2 +x + 7 is divided by x2 + 1, find the results:
2x4 - 9x3 + 13x2 - 15x + 9 = 2x4 - 6x3 - 3x3 + 9x2 + 4x2 - 12x - 3x + 9 = 2x3(x - 3) - 3x2(x - 3) + 4x(x - 3) - 3(x - 3) = (x - 3)*(2x3 - 3x2 + 4x - 3) So the quotient is (2x3 - 3x2 + 4x - 3) and the remainder is 0.
4x2 = -12x, divide both sides by 4x: x = -3
X=3 y=2 (3x3) + (4x2) = 17 9 + 8 = 17
We're on it . . .6x3 + 4x2 = 2xSubtract 2x from each side:6x3 + 4x2 - 2x = 0Divide each side by 2:(Don't divide by 'x' ... you'll lose a root.)3x3 + 2x2 -x = 0Factor the left side:x (3x2 + 2x - 1) = 0x (3x - 1) (x + 1) = 0x = 0x = 1/3x = -1
The idea is to add like terms together - in this case, the terms that have the variable "x" raised to the same power.
4x^2 = 12 Divide through by '4' x^2 = 3 Square root both sides x = +/-sqrt(3)
Take out the common factor, which in this case is 4x2. Divide each of the terms by this common factor. 12x2 - 4x3 = 4x2(3+x)
4x2-x+2x2 is 6x2-x when simplified
If you mean: 4xsquared+40x+100 then divide all terms by 4 which then factors to (x+5)(x+5)
Divide all terms by 4:- x2+5x-6 = (x-1)(x+6) when factored
12x * 4x2 = 48x3
