Step-by-step explanation:
→ Option A
x² - 11x + 28
= (x - 7)(x - 4) ❎
→ Option B
x² - 6x + 8
= (x - 4)(x - 2) ❎
→ Option C
x² + 7x + 12
= <u>(x + 4)</u>(x + 3) ✔️
Answer:
heyyy I will try My best to help you
Answer:
25°
Step-by-step explanation:
The angle of a right triangle is always 90°. 90-35=51. 25 times 2 is 50 plus 1 is 51, so x is 25°.
Answer:
B should be the answer but it could but C
The equation of the quadratic function is f(x) = x²+ 2/3x - 1/9
<h3>How to determine the quadratic equation?</h3>
From the question, the given parameters are:
Roots = (-1 - √2)/3 and (-1 + √2)/3
The quadratic equation is then calculated as
f(x) = The products of (x - roots)
Substitute the known values in the above equation
So, we have the following equation

This gives

Evaluate the products

Evaluate the like terms

So, we have
f(x) = x²+ 2/3x - 1/9
