Using the quadratic equation formula:
x = -2 plus or minus the square root of 6 which means that
x = 0.4494897427831779
x = -4.4494897427831779
4x2 + x2 = 8 + x2
x2-5-4x2+3x = 0 -3x2+3x-5 = 0 or as 3x2-3x+5 = 0
4x2 - 30 = 34 ⇒ 4x2 = 64 ⇒ x2 = 16 ⇒ x = 4 or -4
5x2-2x+16=4x2+6x ,or x2-8x+16=0, or x2-2(x)(4)+(4)2=0, or (x-4)2=0, or (x-4)(x-4)=0, or x=4
10x2 - 64 = 36 + 6x2; whence, 4x2 - 100 = 0, x2 = 25, and x = ±5.
Answer : x = ± 1 4x2 - 30 = 34 : 4x2 = 34 - 30 = 4 4x2 = 4 : x2 = 1 therefore x = √1 = ± 1
It has two equal solutions of 2
Given 3x3 + 4x2 +x + 7 is divided by x2 + 1, find the results:
x2+7x+3 = 0 Using the quadratic equation formula the solutions are:- x = -6.541381265 or x = -0.4586187349
2 this Domo
x3 + 4x2 + 6x + 24 = (x2 + 6)(x + 4)
x3 + 4x2 + x + 4 = (x + 4)(x2 + 1)
