y = x2-4x+4 Since the highest degree term is 2, it must have 2 roots
What is the factor of x-4x plus 4?
x - 4x + 4 = -3x + 4 which cannot be factorised.
Factor 4x squared plus 8x plus 4?
4x2 + 8x + 4 = 4 (x2 + 2x + 1) = 4 (x + 1)2
What is the x-intercept for y equals 4x-16?
y = 4x - 16At the x-intercept, y=0.0 = 4x - 16Add 16 to each side:16 = 4xDivide each side by 4:x = 4
How do you factor 20x2-9x-20?
(a + 4)(a - 5)
How do you solve 4x-5y plus 20 equals 0?
4x-5y+20 = 0 -5y = -4x-20 y = 4/5x+4 which is now in slope intercept form
How do you solve -20 equals -4x plus 6?
-20 = -4x +6 add 20 to both sides 0 = -4x +26 4x = 26 x = 26/4 = 6.5
What is the substitution of4x plus 4y equals 16 and y equals 5?
4x+4y=16 y=5 4x+ 20=16 4x=-4 x=-1
What is the x-intercept of y equals -4x plus 4?
x-intercept of y equals -4x plus 4 y = -4x + 4 0 = -4x + 4 -4 = -4x 1 = x So 1 is the x-intercept
2x plus x plus 4 plus 2x equals x plus 20?
2x + x + 4 +2x = x + 20 5x + 4 = x + 20 5x - x = 20 - 4 4x = 16 x = 4
What is the answer to 9x plus 3-25 equals 4x-2?
9x+3-25 = 4x-2 5x = 20 x = 4

How do you solve 3x plus 2y equals 4 4x plus 3y equals 7?
You need to organise your question properly. 3x+2y=4 4x + 3y= 7? Is 4 4x = 44x or 4-4x or 4+4x How can there be 2 equal signs in 1 equation?
Indentify the slope of 4x plus 5y equals 20?
4x + 5y = 20 5y = -4x + 20 y = (-4/5)x + 20/5 Now that the equation has been rewritten in standard form, the slope is the cofficient of x, -4/5 [or -0.8]
What is the answer to 4x plus 5y equals -20?
Slope-line form is: y = -4(x/5 + 1)
