Question

4x^2 + 7x + 3 factorise it using identity that is (a^2 + 2ab + b^2)​

Answer 1

Answer:

should, however, be noted that 7×(xy) is not an irreducible form of 7xy since the factor xy can be further expressed as a product of x and y, i.e., xy = x×y. Let’s consider another expression 5x (x+4). It can be written as a product of factors. 5, x and (x+2). 5x(x+4) = 5×x×(x+4). The factors 5, x and (x+4) are irreducible factors of 5x (x+4)

Answer 2

Step-by-step explanation:

7x=4x + 3x

4x^2 + 4x +3x + 3

4x(x+1)+3(x +1)

(x+1)(4x+3)
