How do you factor x squared mines 9x plus 8?
x2 - 9x + 8 = (x-1)(x-8)
Factor x squared minus 9x plus 8?
x2-9x+8=0 has two solutions:x = 8x = 1
Solution for quadratic equation x2 plus 9x equals - 8?
x2+9x=-8 or x2+9x+8=0 (x+8)(x+1)=0 x=-8,-1 check answer: (-8)2+9(-8) = -8? and (-1)2+9(1) = -8? 64 - 72 is equal to -8. 1 - 9 is equal to -8. x= -8 and x= -1 are both solutions.
Polynomial x2 plus 9x plus 8 Enter each factor as a polynomial in descending order?
(x + 8)(x + 1)
What is 9x-8 equals 46?
9x - 8 = 46 9x = 46 +8 9x= 54 9x/9 = 54/9 x= 6

Factor x squared minus 9x plus 8?
x2-9x+8=0 has two solutions:x = 8x = 1
How do you factor x2-9x plus 8?
(x-9)(x+9)
What are the points of intersection of the curves y equals x2 -7x plus 8 and y equals -x2 plus 9x -6 showing work?
If: y = x2-7x+8 and y = -x2+9x-6 Then: x2-7x+8 = -x2+9x-6 So: 2x2-16x+14 = 0 => x2-8x+7 = 0 Therefore: x = 1 and x = 7 By substitution: x =1, y = 2 and x = 7, y = 8 Points of intersection: (1, 2) and (7, 8)
How do you factor the polynomial x2 plus 9x plus 8 with each factor as a polynomial in descending order?
(x + 8)(x + 1)

What is 9x-8 equals 46?
9x - 8 = 46 9x = 46 +8 9x= 54 9x/9 = 54/9 x= 6
How do you factor x2 - 9x -8?
To factor the quadratic expression x^2 - 9x - 8, we need to find two numbers that multiply to -8 (the constant term) and add up to -9 (the coefficient of the x-term). The two numbers are -1 and 8. Therefore, we rewrite the middle term -9x as -x - 8x. Now, we can factor the expression as (x - 8)(x + 1).
How do you solve 44 equals 9x plus 8?
44 = 9x +8 36=9x 4=x
What are the points of intersection of the following parabolas y equals x2 -7x plus 8 and y equals -x2 plus 9x -6?
y = x2 - 7x + 8 y = -x2 + 9x - 6 subtract the 2nd from the 1st equation 0 = 2x2 - 16x + 14 simplify 0 = x2 - 8x + 7 factor it, since 7 = (-1)(-7) and -1 - 7 = -8 0 = (x - 1)(x - 7) let each factor equal to zero x - 1 = 0 or x - 7 = 0 solve for x thus, x = 1 and x = 7. Chose one of the equation and substitute x with 1, and 7 to find the corresponding y-values. y = x2 - 7x + 8 y = (1)2 - 7(1) + 8 = 1 - 7 + 8 = 2; (1, 2) intersection point y = (7)2 - 7(7) + 8 = 49 - 49 + 8 = 8; (7, 8) intersection point
What is the answer to 9x minus 4 equals 7x plus 8?
9x-4 = 7x+8 9x-7x = 8+4 2x = 12 x = 6
