Answer:
Step-by-step explanation:
The least number of degree is 3 and the third root should be (4 - i) to make polynomial rational.
<u>The polynomial is:</u>
- (x - 3)(x - (4 + i))(x - (4 + i)) =
- (x - 3)(x² -x(4 + i + 4 - i) + (4 + i)(4 - i)) =
- (x - 3)(x² - 8x + 16 - (-1)) =
- (x - 3)(x² - 8x + 17) =
- x³ - 8x² + 17x - 3x² + 24x - 51 =
- x³ - 11x² + 41x - 51
Answer:
6x
Step-by-step explanation:
Combining like terms is simply representing them as a single term. With algebra, you can perform arithmetic on the coefficient (the 10 and the 4) to simplify the expression, giving you 6x.
Answer:
<em>It has been given that Rectangle Q has an area of 2 square units.</em>
<em>Thea Drew a scaled version of Rectangle Q and marked it as R.</em>
<em>As you must keep in mind If we draw scaled copy of pre-image, then the two images i.e Pre-image and Image are similar.</em>
<em>As you have not written what is the scale factor of transformation</em>
<em>Suppose , Let the Scale factor of transformation= k</em>
<em>Rectangle Q = Pre -image, Rectangle R= Image</em>
<em>If, Pre-Image < Image , then scale factor is k >1.</em>
<em>But If, Pre-Image > Image , then Scale factor will be i.e lies between, 0<k<1.</em>
