Question

(x + 6) (4x + 8) =

Answer 1

You have to use binomial expansion.

y=(x + 6)(4x + 8)
y=x(4x + 8) + 6(4x + 8)
y=4x^2 + 8x + 12x + 48
y=4x^2 + 20x + 48

\[(x+6)(4x+8)=4x^2 + 20x + 48\]

Answer 2

(x + 6)(4x + 8)
Multiply x 4x\[4x \times x = 4x ^{2}\] then,
multiply 8 by x
8(x) = 8x then,
multiply 6 by 4x
6(4x) = 24x then,
multiply 6 by 8
6(8) = 48 then
write the equation which is;\[4x ^{2}+8x+24x+48\]\[=4x ^{2}+32x+48\]IN SHORT
(x+6)(4x+8)
\[=4x ^{2}+8x+24x+48\]\[=4x ^{2}+32x+48\]
