What is the positive solution of the equation 3x2 plus 15x-42 equals 0?
2
X2 plus 8x equals -3x2 plus 5?
x2+8x = -3x2+5 4x2+8x-5 = 0 (2x+5)(2x-1) = 0 x = -5/2 or x = 1/2
How do you solve 3x squared plus 2x equals 16?
3x2 + 2x = 16 ∴ 3x2 + 2x - 16 = 0 ∴ 3x2 - 6x + 8x - 16 = 0 ∴ 3x(x - 2) + 8(x - 2) = 0 ∴ (3x + 8)(x - 2) = 0 ∴ x ∈ {-8/3, 2}
Solve 3xsqaured plus x minus 2 equals 0?
3x2 + x - 2 = 0(3x - 2) (x + 1) = 0x = + 2/3x = -1
What is the solution set for 3x2 - 6x equals 0?
x = 0 or x = 2
What is the positive solution of the equation 3x2 plus 15x-42 equals 0?
2
3x2 plus 8x plus 4 equals 0?
(3x + 2)(x + 2) so x = -2/3 or -2
What is the fifth step in solving the eqution by completing the square 3x2 plus 14x plus 8 equals 0?
3x2+14x+8 = 0 x = -2/3 or x = -4
Put the equation in the form ax2 plus bx plus c equals 0 x2-3 equals 3x2 plus 8x?
2x^2 + 8x + 3 = 0
X2 plus 8x equals -3x2 plus 5?
x2+8x = -3x2+5 4x2+8x-5 = 0 (2x+5)(2x-1) = 0 x = -5/2 or x = 1/2
How do you solve 3x squared plus 2x equals 16?
3x2 + 2x = 16 ∴ 3x2 + 2x - 16 = 0 ∴ 3x2 - 6x + 8x - 16 = 0 ∴ 3x(x - 2) + 8(x - 2) = 0 ∴ (3x + 8)(x - 2) = 0 ∴ x ∈ {-8/3, 2}
Solve 3xsqaured plus x minus 2 equals 0?
3x2 + x - 2 = 0(3x - 2) (x + 1) = 0x = + 2/3x = -1
What is 3x2 plus 30x plus 48?
3x2 + 30x + 48 is a quadratic polynomial. If 3x2 + 30x + 48 = 0, then: 3(x + 2)(x + 8) = 0 ⇒ x + 2 = 0 → x = -2 or x + 8 = 0 → x = -8
How do you get 2 plus 2 equals 6?
2+2=4-1=3x2=6
What is the solution set for 3x2 - 6x equals 0?
x = 0 or x = 2
Factorize completely 3x2-5x plus 2?
If you meant 3x2 - 5x + 2, here is your answer 3x2 - 5x +2 = 0 => 3x2 - 3x - 2x + 2 = 0 => 3x(x-1) - 2(x-1) = 0 => (3x - 2) (x-1) = 0 => x = 2/3 or, x = 1
X2 plus 7x equals -2x2 plus 6?
x2+7x=-2x2+6 3x2+7x-6=0 (3x-2)(x+3)=0 3x-2=0 or x+3=0 x=2/3 or x=-3
