Question

(x+4) (x + 10)


please answer it​

Answer 1

Answer:

x²+14x+40

Step-by-step explanation:

(x+4)(x+10)

We know that, (x+a)(x+b)= x²+(a+b)x+ab

Here, a=4 and b=10

∴ (x+4)(x+10)= x²+(4+10)x+4×10

⇒x²+14x+40

Answer 2

Answer

• x² + 14x + 40

Given

• ( x + 4 ) ( x + 10 )

To Find

• Solve the equation

Solution

$\tt (x+4)(x+10)\\\\\implies \tt x^2+10x+4x+40\\\\\implies \tt x^2+14x+40$

More Info

$\bullet \;\; \tt (x+a)(x+b)=x^2+x(a+b)+ab\\\\\bullet \;\; \tt (x+y)^2=x^2+y^2+2xy\\\\\bullet \;\; \tt (x-y)^2=x^2+y^2-2xy\\\\\bullet \;\; \tt (x+y)(x-y)=x^2-y^2$
