Quadratic is in the form
ax^2+bx+c=0
so distribute and stuff and simplify
remember
a(b+c)=ab+ac
(x+2)^2+5(x+2)-6=0
remember order of opertaions
(x+2)(x+2)+5(x+2)-6=0
x^2+4x+4+5x+10-6=0
add like terms
x^2+9x+8=0
Answer:
Use photo math, it will explain it all in different forms
Answer
D. X>5
Step by step explanation
x - 8 > -3
Here we have to find the value of x.
Add 8 on both sides, we get
x - 8 + 8 > -3 + 8
x > 5
Thank you.
Answer:
x = 20
Step-by-step explanation:
The triangle is isosceles ( 2 congruent sides )
Hence the base angles are congruent, thus
3x = 60 ( divide both sides by 3 )
x = 20
