Answer:
(x + + )(x + - )
Step-by-step explanation:
solve the polynomial for x then express in product of factor form
Solve
x² + x - 10 = 0 ( add 10 to both sides )
x² + x = 10
Using the method of completing the square
add ( half the coefficient of the x- term )² to both sides
x² + 2( )x + = 10 +
(x + )² = ( take the square root of both sides )
x + = ± = ± ( subtract from both sides )
x = - ±
Thus corresponding factors are
(x - (- - ) ) and (x - (- + ), that is
(x + + ) and ( x + - )
Thus
x² + x - 10 = ( x + + )(x + - ) ← in factored form
Answer:36
Step-by-step explanation:36÷ -4 = -9
Isn’t it a poem?? And tbh it was good. I’d rate it a 8/10
Answer:
2.8 + 2x = 0.6
______
8
multiply by 8 to both sides
x8 x8
2.8 + 2x = 4.8
subtract 2.8 from both sides
-2.8 -2.8
2x = 2
divide by 2 from both sides
/2 /2
x = 1
