What is x if x plus -2.5 plus 6.8 equals 0?
x+(-2.5)+6.8=0x+(-2.5+6.8)=0x+(4.3)=0x+4.3=0Subtract 4.3 from both sides and you get:x= -4.3
What are the roots of the quadratic equation x2 - 14x plus 45 equals 0?
x2-14x+45=0(x-9)(x-5)=0x-9=0 & x-5=0x=9 & x=5
Why does x equal to 8 and 0 in x2 equals 8x?
x2 = 8xx2- 8x = 0x(x - 8) = 0x = 0 ;x - 8 = 0x = 8
What is X when x2 plus 0x - 2.25 equals 0?
X2+0X - 2.25=01.= Both sides by 2.25X2+0X=2.252. Subtract both sides by 0XX2=2.253. Square root both sidesX=1.5
What is 12x3 plus 17x2 plus 5x?
12x^3+17x^2+5x=0x(12x^2+17x+5)=0x(x+1)(12x+5)=0x=0x=-1x=-5/12
What is x if x plus -2.5 plus 6.8 equals 0?
x+(-2.5)+6.8=0x+(-2.5+6.8)=0x+(4.3)=0x+4.3=0Subtract 4.3 from both sides and you get:x= -4.3
What is the solution for the equation x plus 1 equals x plus 2?
x+1=x+2 x=1+2+x 0x=1+2 0x=3 0x=/=3 (=/= means does not equal) so there is no solution
X2-10x plus 25 equals 0?
x2 - 10x + 25 = 0(x - 5)(x - 5) = 0x - 5 = 0x = 5
What is x if x plus 4x equals 0?
x + 4x = 05x = 0x = 0/5x = 0
X plus y equals 9x plus y x is eaqual to?
x + y = 9x + y9x + y = x + y8x + y = y8x = 0x = 0
X²-7x plus 12 equals 0?
x2-7x+12 = 0 (x-3)(x-4) = 0x=3,4
How do you solve this equation x3 plus 13x2 equals -22x?
x3+13x2=-22xadd 22x to both sides:x3+13x2+22x=0now factor:x(x2+13x+22)=0x(x+11)(x+2)=0x=0x+11=0x+2=0Therefore the solution to this equation is x=0, x=-11, x=-2
What are the roots of the quadratic equation x2 - 14x plus 45 equals 0?
x2-14x+45=0(x-9)(x-5)=0x-9=0 & x-5=0x=9 & x=5
Why does x equal to 8 and 0 in x2 equals 8x?
x2 = 8xx2- 8x = 0x(x - 8) = 0x = 0 ;x - 8 = 0x = 8
Solve for x x2 plus 12x plus 36 equals 0?
x^2 + 12x + 36 = 0(x + 6)(x + 6) = 0(x + 6)^2 = 0√(x + 6)^2 = ± √0x + 6 = 0x + 6 - 6 = 0 - 6x = 6
X squared plus 2x - 15 equals 0?
x2 + 2x - 15 = 0(x + 5) (x - 3) = 0x = -5x = +3
What is X when x2 plus 0x - 2.25 equals 0?
X2+0X - 2.25=01.= Both sides by 2.25X2+0X=2.252. Subtract both sides by 0XX2=2.253. Square root both sidesX=1.5
