Answer:
a=x and b=9
(x+9)(x−9)
Explanation:
Since both terms are perfect squares, factor using the difference of squares formula, a2−b2=(a+b)(a−b)
Answer:
Step-by-step explanation:
<u>Given line:</u>
<u>Points on the same line:</u>
- (2a, -4a + 3) and (2b - 3, b)
<u>Substitute x and y values of both points into equation of the line and solve for a and b:</u>
- -4a + 3 = -3(2a) - 2 ⇒ -4a + 3 = -6a - 2 ⇒ 6a - 4a = -2 - 3 ⇒ 2a = -5 ⇒ a = -2.5
- b = -3(2b - 3) - 2 ⇒ b = -6b + 9 - 2 ⇒ b+ 6b = 7 ⇒ 7b = 7 ⇒ b = 1
