Solve 3x to the 2nd power equals 21 what are the solutions x equals and what is the x intercept?
3x2 = 21 describes two single values, and does not have an x intercept. 3x2 = 21 ∴ x2 = 7 ∴ x = ±√7
What is 3x2-4x plus 7 when x equals -2?
3x2= 6 6-(4x-2)= 6--8= 6+8 = 14 14+7 = 21
3X2 plus X equals -7?
3 x 2 + x = -7 >> 6 + X = -7 >>> x = -13
2x1 plus 3x2 plus 7x3 equals 12?
No. 7*3, alone, is bigger than 12.
What is the factor of 3x2 plus 22x plus 7 equals?
3x2 + 22x + 7 = 3x2 +21x + x + 7 = 3x(x + 7) + (x + 7) = (x + 7)(3x + 1)
