Question

14. What is the product of (*+ a) and (x +
b)
a) x + (a - b)x+ ab
b)x-(a+b)x+ ab
c) x + (a + b) - ab
d) x + (a + b) + ab​

Answer 1

Answer:

We know, (x + a)(x + b) = x2 + (a + b)x + ab. Therefore, (z + 1)(z + 3) = z2 + (1 + 3)z + 1 ∙ 3. 2. Find the product of (m - 3)(m - 5) using the standard formula.
