we are given
x^2-4x-5
we can use formula
x^2-(a+b)x+ab=(x-a)(x-b)
so, we have
a+b=4
ab=-5
now, we can solve for a and b
and we get
a=5, b=-1
now, we can plug it in formula
x^2-4x-5=(x-5)(x+1) ............Answer
Answer:
x = 23
Step-by-step explanation:
60°=x+14
60+14=84=X
Simplify x3/x A.x2 B. 1/x2 - 3705076. ... + 4 f(x) = x2 – 5x + 4 f(x) = x2 + 3x – 4 f(x) = –2x2 + 10x – 8 f(x) = –4x2 – 16x – 1.
Y = m + 3
you have to count the ones in between and add the 3 to fill in for b
12x^2-x-35
12x^2-21x+20x-35
3x(4x-7)+5(4x-7)
(4x-7)(3x+5)
Either,
x=7/4
Or,
x=-5/3
