Question

factorisation one example​

Answer 1

Answer:

Example: (x+2)(x+3) = x2+ 2x + 3x + 6 = x2+ 5x + 6. Here, 5 = 2 + 3 = d + e = b in general form and 6 = 2 × 3 = d × e = c in general form. To factorize quadratic polynomial, we shall be looking for numbers which on multiplication will get equal to c and on summation equal to b.

Answer 2

9y-16

(3y)2-(4)2 (a2-b2=(a+b)(a-b)

(3y+4)(3y-4)
