Answer:
Use the quadratic formula
=−±2−4√2
x=−b±b2−4ac2ax=\frac{-{\color{#e8710a}{b}} \pm \sqrt{{\color{#e8710a}{b}}^{2}-4{\color{#c92786}{a}}{\color{#129eaf}{c}}}}{2{\color{#c92786}{a}}}x=2a−b±b2−4ac
Once in standard form, identify a, b, and c from the original equation and plug them into the quadratic formula.
2+5+6=0
x2+5x+6=0x^{2}+5x+6=0x2+5x+6=0
=1
a=1a={\color{#c92786}{1}}a=1
=5
b=5b={\color{#e8710a}{5}}b=5
=6
c=6c={\color{#129eaf}{6}}c=6

Answer:
x= - 2 or x = - 3
Step-by-step explanation:
Identify the center and radius of the circle (x+4)^2 + (y-2)^2=16
Answer:
X=-7
Step-by-step explanation:
Divide then subtract to get x by itself
-30=5(x+1)
Divide each side by 5= -30/5=5(x+1)/5
-30=x+1
-6=x+1
-6-1=x+1-1 Subtract one to get x by itself
-6-1=x+1-1 (cross out both x's.
-6-1=x

Fill in the blanks with the correct numbers.
Answer:
12^2 + 43x + 35
Step-by-step explanation:
(3x+7)(4x+5)
=(3x+7)(4x+5)
=(3x)(4x)+(3x)(5)+(7)(4x)+(7)(5)
=12x2+15x+28x+35
=12x2+43x+35
